I am trying to install conda packages/create environments behind a corporate firewall
On another machine, I managed to install packages from conda default channels by setting the HTTP/HTTPS proxies and ssl_verify: False in conda config.
However, I am now getting ProxyError: Conda cannot proceed due to an error in your proxy configuration. Check for typos and other configuration errors in any '.netrc' file in your home directory, any environment variables ending in '_PROXY', and any other system-wide proxy configuration settings.
I have verified that conda is not accessing any .netrc file through conda info
.condarc:
channels:
- defaults
# Show channel URLs when displaying what is going to be downloaded and
# in 'conda list'. The default is False.
show_channel_urls: True
allow_other_channels: True
proxy_servers:
http: http://abc.cde.local:XXXX
https: https://abc.cde.local:XXXX
ssl_verify: False
Here are the steps I have tried to resolve my issue:
I have verified that the proxy URLs are correct and can make outgoing requests through these URLs
I have tried to set the two settings both through conda config --set and .condarc
I have tried to set the proxies through environmental variables
I cannot make changes to Windows proxy settings or do anything that requires any admin permissions.
Does anyone have any experience with this?
If you know your condarc file is correct, on Windows you need to make sure that your environment variables are "http_proxy" and https_proxy", lowercase.
Also, most proxies use an unencrypted traffic to the proxy. So make sure the URLs to your proxy are both http://
Finally, when you change your enviroment variables in Windows you must start a new powershell session for the changes to take affect.
This and the correct conda RC file solved it for me.
I am trying to install packages from within the corporate network along with some packages that exist within the corporate repository. I was able to configure the following proxy settings for yarn
yarn config set proxy "${PROXY}"
yarn config set https-proxy "${PROXY}"
But since some packages exist within the corporate network installing them fails. I couldnt find a way to set no proxy for internal corporate urls. There is a workaround posted here - https://github.com/yarnpkg/yarn/issues/5048#issuecomment-604181595. But I would like to know if there is a better way
yarn doesn't seem to to have a concept of no proxy. It either tries to proxy everything or nothing...very naive. Fortunately, npm does so we use npm for all of our projects.
I have been trying to do the quickstart guide for react native, but kept getting this error
There appears to be trouble with your network connection. Retrying...
My connection works just fine.
This happens when your network is too slow or the package being installed is too large, and Yarn just assumes it's a network problem.
Try increasing Yarn network timeout:
yarn add <yourPackage> --network-timeout 100000
Deleting the yarn.lock file and rerunning "yarn install" worked for me.
I got this issue because I was working within my company internal network and proxy needed to be set.
$ yarn config set proxy http://my_company_proxy_url:port
$ yarn config set https-proxy http://localhost:3128
example $ yarn config set https-proxy http://proxy.abc.com:8080
Simple working solution (right way of doing it):
Looks like yarn was trying to connect via a proxy. The following worked for me:
npm config rm proxy
npm config rm https-proxy
Source
Turning off "real time protection" with windows defender fixed it for me.
Sucks but it appears the checks are too much for yarn to handle.
Could be that your network speed is too slow and timeout is relatively short, you can set yarn install --network-timeout=30000
If you still have the error, could be solved by proxy, vim ~/.yarnrc and add useful proxy setting.
yarn config set network-timeout 600000 -g
Often, your error is caused by hitting the network connection time limit, and yarn simply reports there is "trouble with your network connection".
The line of code at the top of my answer sets the global yarn network timeout to 10 minutes.
Having a long network timeout is probably okay, because yarn uses caches and if it's big and you don't have it, you probably want it to just go ahead and take the time to download.
Could be a proxy issue. Run the command below to delete the proxy.
yarn config delete proxy
The following helped me
yarn config delete https-proxy
yarn config delete proxy
they set your https-proxy and proxy values to undefined. My https-proxy was set to localhost. Check that proxy and https-proxy config values are undefined by using the following
yarn config get https-proxy
yarn config get proxy
The large package involved often can be Material Design Icons.
Check if you make use of the Material Design Fonts material-design-icons in your package.json and remove it!
material-design-icons is too big to handle and you should only use material-design-icons-fonts if you only need them.

Turn off or disable your antivirus before run this command. I am also facing same issue than i disable quick heal antivirus and it is works.
create-react-app my-app
When I want to use yarn I have above error, but there is not any error with npm, for this situation you can install react project from npm
npx create-react-app app --use-npm
Deleting the yarn-lock file, doing a yarn cache clean and then a yarn solved my issue
npm install
worked for me (but my project was built with yarn)
Got the exact issue when trying yarn install
yarn install --network-timeout 100000
Just using this didn't solve my problem. I had to install only ~5 packages at a time. So I ran yarn install multiple times with only few dependencies in the package.json at a time.
Hope this helpful
In short, this is caused when yarn is having network problems and is unable to reach the registry. This can be for any number of reasons, but in all cases, the error is the same, so you might need to try a bunch of different solutions.
Reason 1: Outdated Proxy Settings
This will throw the "network connection" error if you are connected to a network that uses a proxy and you did not update yarn configs with the correct proxy setting.
You can start running the below commands to check what the current proxy configs are set to:
yarn config get https-proxy
yarn config get proxy
If the proxy URLs returned are not what you expect, you just need to run the following commands to set the correct ones:
yarn config set https-proxy <proxy-url>
yarn config set proxy <proxy-url>
Similarly, if you have previously set up the proxy on yarn but are no longer using a network connection that needs a proxy. In this case, you just need to do the opposite and delete the proxy config:
yarn config delete https-proxy
yarn config delete proxy
Reason 2: Incorrect Domain name resolution
This will throw the "network connection" error if for whatever reason your machine cannot resolve your yarn registry URL to the correct IP-address. This would usually only happen if you (or your organization) are using an in-house package registry and the ip-address to the registry changes.
In this case, the issue is not with yarn but rather with your machine. You can solve this by updating your hosts file (for mac users, this should be found in '/etc/hosts') with the correct values, by adding a mapping as follows:
<ip-address> <registry-base-url>
example:
10.0.0.1 artifactory.my.fancy.organiza.co.za
Adding option --network=host was the solution in my case.
docker build --network=host --progress=plain .
I encountered this error while attempting yarn outdated. In my case, a few of the packages in my project were hosted in a private registry within the company network. I didn't realize my VPN was disconnected so it was initially confusing to see the error message whilst I was still able to browse the web.
It becomes quite obvious for those patient enough to wait out all five retry attempts. I, however, ctrl-c'd after three attempts... 😒
In my case I found a reference to a defunct registry in my ~/.yarnrc file
When I removed that the error went away
This happened in my case trying to run yarn install.
My project is a set of many sub-projects.
After a couple of retries, it showed a socket-timeout error log:
error An unexpected error occurred: "https://<myregitry>/directory/-/subProject1-1.0.2.tgz: ESOCKETTIMEDOUT".
I cloned subProject1 separately, did yarn install on it and linked it with main project.
I was able to continue with my command on main project after that.
Once done, I unlinked the subProject1 and did a final yarn install --force which was success.
I got this error while trying to run yarn install - i use WSL with ubuntu distro, the following command fixed it,
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null
This may be a late answer but here are some possible reasons:
If you are behind a proxy you may need to configure .npmrc if you are using npm or .yarnrc if you are using yarn
If proxy is well setup, you may need remove yarn.lock or package-lock.json and re-run npm i or yarn
If you are working within a docker environment or elsewhere that might need a different approach where you are not modifying the installation process, try adding a file named .yarnrc in the root of the project with the problem (where your package.json resides) and in that file write:
network-timeout 600000
Docker will still run without modifying the docker-compose.yml file and you get the timeout solution.
I faced the same issue but adding VS Code to the Firewall Exception List has solved my issue.
I got the same issue but my case is totally different. I am on Linux, and I get this error because I had a service nginx status off.
I am trying to work on a Go open source project, on a corporate device. Attempts to address the dependencies via dep ensure command always return 407 PROXY AUTH required. I do have http_proxy and https_proxy environment variable set with values in the format http://user:pasword#proxyname:proxyport. I have also attempted to set the git configs http.proxy. But I do get the same error. What am I missing?
Thanks
This is owing to Git client configuration issues and mismatch between git binary and gnutls. I have had to recompile git binary using openssl, to get this to work.
I think this is a very common issue among those who want to use Cargo with Windows at work; I have seen multiple GitHub issues and forum posts related to it, but none of the answers solved my problems.
Whenever I try to build some code pointing to a crates.io crate, I get the following error:
Downloading <package>
error: unable to get packages from source
Caused by:
failed to download package <package> from <package address>
Caused by:
SSL connect error
What can I do to fix this? I know that Cargo can use the settings at .cargo/config and that the proxy details can be included there, but it doesn't work for me, with or without specifying the path for the certificate (I used the one distributed with curl), like below:
[http]
proxy = "http://user:password#proxy-address.xyz:port"
cainfo = "cert.pem"
[https]
proxy = "https://user:password#proxy-address.xyz:port"
cainfo = "cert.pem"
The proxy specified in the config file works for any other purpose.
I'm using Windows 7 64bit, Rust 1.11 GNU and Cargo bundled with it. How can I get this working? Currently I have to resort to downloading crate sources manually from their repositories and specifying paths = [...] for each of them in the Cargo config file.
I had the same problem, and I solved simply setting environment variables http_proxy and https_proxy with http(s)://user:password#proxy-address.xyz:port.
The only annoiyng part is that, when you need to unset the proxy (e.g. when you are smart-working from another network without using company's VPN) you have to unset / delete those variables.
It appears that this is no longer an issue as of cargo 0.13 bundled with Rust 1.13 stable - I no longer need to manually download packages and put them in paths in cargo's config file.
