Using postman desktop Version 10.8.7
Windows 10
SSL certificate verification - Off
Using System proxy
Created a docker image and running the file on --port 8080 and --host 0.0.0.0
The image is running successfully but when using the localhost:port URL for requesting the data from the file, every time its getting timed out.
But same thing is getting executed in Ubuntu OS.
If anyone faced the same issue before, please help me out on this.

I'm trying to pull a simple hello-world image from docker hub using :
docker run hello-world
But I'm getting this error on Windows 7 :
Unable to find image 'hello-world:latest' locally
C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: Get https://registry-1.docker.io/v2/: authenticationrequired.
I've tried so many different things but none seem to work :
1 - I tried logging in, but I'm getting the same error :
docker login
Tried my username, my email ... Same error :
Error response from daemon: Get https://registry-1.docker.io/v2/: authenticationrequired
2 - Restarted docker machine, same error.
3 - Reinstalling Docker and Oracle VirtualBox multiple times
4 - Done all the steps here : https://github.com/docker/kitematic/wiki/Common-Proxy-Issues-&-Fixes
I really don't know how to fix this anymore.
I had this problem when I tried to login to the docker behind a corporate proxy. Are you in a similar situation? If so, see if you add "https://registry-1.docker.io/v2/" to the exemption list for proxy's HTTPS analysis.
If you are not behind a proxy, check to see if you have any software that do a HTTPS analysis. Sometimes software like Fiddler or Antivirus does that. If you found anything like that see if you can whitelist the url
Hope it helps. I had a hard time figuring this out for my issue
I have started my app locally and reach it fine on http://localhost:3000
But when trying to access it throuhg the cypress tool I get 502 bad gateway. Anyone knows why this differ from it working just fine in Chrome to access it?
Faced the same issue when running Angular app in localhost. App was running in chrome but not in cypress tool giving 502 bad gateway error. I builded the angular app by ng-build command and served using command http-server -p 4200 -c-1 dist/your_poject_name. When running http-server command, got as below:
Starting up http-server, serving dist
Available on:
http://10.132.14.98:4200
http://127.0.0.1:4200
Use the url http://10.132.14.98:4200 in cy.visit and now bad gateway error does not come. The problem is with using 127.0.0.1 or localhost in the url. Anything other than localhost and 127.0.0.1 works. Hope this information helps.
Recently started to use Docker in Windows because that's the enviroument where I work. I don't have any problem connecting WSL with Windows Docker an using it for first instance.
After reboot my laptop the problems cames to me. When I'm trying to create an image I get the next error:
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
Is so weird beacause if uninstall windows docker and reinstall it, everything works but if reboot or shut down my laptop, the problem comes again.
It seems like DNS resolve issues about Docker registry.
Sometimes DNS on DHCP information or your network settings makes this trouble on windows.
Try to change DNS options from Automatic to Fixed GoogleDNS(8.8.8.8) on Docker for Windows settings.
Please refer this screenshot.

I am following this tutorial on using docker images, and I am at the stage to run the example docker image like follows:
docker run -p 4000:80 friendlyhello
On the command line it seems ok:
>docker run -p 4000:80 friendlyhello
* Running on http://0.0.0.0:80/ (Press CTRL+C to quit)
but when I try to open the page http://localhost:4000 on a web browser, it seems to be unable to connect (Safari and Firefox). On Firefox the error message is
Unable to connect
Firefox can't establish a connection to the server at localhost:4000.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
I also checked the file /etc/hosts and it contains the following entry
127.0.0.1 localhost
So what could be the problem?
I found this solution and tried the following command:
docker run -p 127.0.0.1:4000:80 friendlyhello
which still leads to the same problem. I also tried to open
`http://localhost:80`
again without success.
I am trying to document my React Components and I am running styleguidist server along side with Laravel development server but the styleguidist server crashes with this error.
You have another server running at port 6060 somewhere, shut it down first
You can change the port using the `serverPort` option in your style guide config:
https://react-styleguidist.js.org/docs/configuration.html
I have configured the styleguidist server to run at port 6060 as to resolve this issue and succeeded to run the server only once. After that I am getting this issue again.
How can i resolve this??
The error is saying you have something else running at that port. Have you tried a different one? If you are running a UNIX system, you can see what is running on that port with:
lsof -i tcp:6060
