I am in a corporate env so I have to use a proxy to reach servers. This works well in postman and in browsers. What I can't reach is localhost in postman but I can reach localhost in the browser.
I am running Postman for Linux Version 6.0.9. I have tried reaching localhost:9082/rest/myapi.... and 127.0.0.1:9082/rest/myapi with both global proxy and system proxy turned on and with either turned on and with non turned on. In all cases I am not able to reach localhost.
What I get as an response is an error page from the proxy server! Someway the call gets out on the network instead of being kept on my machine.
The postman console:
My request headers are:
Cache-Control →no-cache
Connection →Keep-Alive
Content-Length →986
Content-Type →text/html; charset=utf-8
Pragma →no-cache
Proxy-Connection →Keep-Alive
My response headers are:
cache-control:"no-cache"
pragma:"no-cache"
content-type:"text/html; charset=utf-8"
proxy-connection:"Keep-Alive"
connection:"Keep-Alive"
content-length:"986"
My response body is an html page.
How can I make a call to localhost work with postman?
I was having similar issue with HTTP calls to local ASP.NET Core Web API apps. Changing the proxy settings didn't fix it for me.
Finally fixed it by turning off File > Settings > General > SSL Certificate Verification
I have the same issue. What works for me is:
Open File -> Settings -> Proxy
Then, enable proxy and put 127.0.0.1 : 80, if your web server runs on 80.
In the git thread, they say it is a known issue, so hopefully it will get resolved soon.
I solved this by Turning off System proxy of Postman.
Open File -> Settings -> Proxy
Then Turn off Use System Proxy
#Menuka Ishan Answer is correct. But in mac only if we change the turn off proxy won't work. You need to turn off the SSL Certificate verification also you need to disable.
I found a temporary solution:
In terminal, go to the directory where postman is installed and add:
machine#dev:~/Documents/Postman$ export NO_PROXY=localhost,127.0.0.1
machine#dev:~/Documents/Postman$ ./Postman
This will make calls to localhost work.
I found a similar problem on Windows machines here
The problem mentioned as an issue here. You should just write a simple batch file like this:
set HTTP_PROXY=
set http_proxy=
set HTTPS_PROXY=
set https_proxy=
START %LOCALAPPDATA%\Postman\Update.exe --processStart "Postman.exe"
open a simple text file, save this as a ".bat" file, and just run it!
I also faced the same issue, but the trick was I implemented both the methods that were stated earlier in the stack.
First I turned off the postman proxy as shown in below image.
Click Settings -> Proxy
And then turned off the SSL certificate verification check button.
Click Settings -> General
And then tried to hit my local server and finally it worked.
While attempting to Get https://localhost:5001/WeatherForecast via PostMan while developing a basic .NET Core (3.1) Web API (on Ubuntu Linux)
I got the error:
Could not get any response There was an error connecting to
https://localhost:5001/WeatherForecast.
I didn't notice the actual solution in the things to try at first, but if you check the highlighted text in the image you will see it.
You can see that the option is turned on in PostMan by default:
I turned the SSL Certificate Verification off and tried again and it worked.
If you are under corporate proxy and you are deploying your webapplication in localhost then no need to set proxy configuration like
http://username:password#corporateProxyServer:ServerPort in postman (Global Proxy Configuration).
As the app is deployed in local machine just use the localhost configuration in setting -> Global Proxy Configuration as :
proxy server : 127.0.0.1
port : 8300 (this is the port where the web application is running )
My problem was that i was setting an invalid Header token and it gave me the error
Error: Header name must be a valid HTTP token ["Accept "]
Warning: This request did not get sent completely and might not have all the required system headers
Just check your Headers.
Adding another potential answer to this for people to check after they've tried the other ideas here.
I was able to solve my own problem by checking the Postman console (View -> Show Postman Console) and then examining the error from the request (in my case it was because I had a newline character on an auth token).
In my case, I had to precede the localhost with https://
These steps solved this issue after 1 whole day struggle:
1) HTTP_PROXY= proxy.company.com:port
HTTPS_PROXY=proxy.company.com:port
to user variables, not to System variables. Make sure the the case is all cap.
2) Updating newtwork driver, and turning on Windows Defender......Make sure you don't see no reds in here.
I was not able to make any calls from postman to docker container running Couchbase Server. Very frustrating. Turns out I had proxy setting configured to some aws instance which has been long deleted.
Goto setting and remove the proxy setting and it worked like a charm on localhost/127.0.0.1/mac laptop eno IP addr or 0.0.0.0
In my case, I was using django-tenants and had to add the domain for the tenant in etc/hosts to get it working on localhosts. My entry for 127.0.0.1 now looks like
127.0.0.1 localhost test.localhost
My problem was forgetting to select Environment. From the drop down where you see No Environment in the image, select the name of your environment.
Menuka Ishan's solution above saved my hours of pain! I left the Global Proxy Configuration switched ON and changed the Proxy Server to 127.0.0.1. Switched OFF the Use System Proxy. I already had the entry 127.0.0.1 localhost in my hosts file under the path C:\Windows\System32\drivers\etc.
If you have active proxy in your system then make sure Global Proxy Configuration and Use System Proxy are turned off. To do this go to Postman preferences > Proxy. You can also try sending a request in postman without typing localhost (e.g. :8080/send)
i think i also found a perfect fix.
First you turn on global proxy configurations, add your local machine Ip which is 127.0.0.1,then also add localhost in the bypass.
Also turn off SSL verification.
It worked for me
This worked for me, i dissable the parrameter host in the header.
HOST Disabled
If anyone is looking for a solution to WooCommerce local install, here are the steps to make this work:
Go to Wordpress Admin > WooCommerce > Settings > Advanced
Create new API key, give it a name
Copy the Consumer Key & Consumer Secret to
your text editor
Open Postman
Create new connection Set the URL for
testing (GET) : http://mylocalsite/wp-json/wc/v3/orders (change
"mylocalsite" to yours)
Click on Authorization tab
Now here is the main change: Although in WC Rest docs, it says to use the "Basic Auth" - IT WILL NOT WORK. Since usually your localhost is HTTP
and not HTTPS. So "Basic Auth" is not relevant in our case.
You will need to change the Authorization to OAuth 1.0
Set Consumer Key & Consumer Secret respectively as it shows in Woocommerce
Click "Send" - it should work now
If still you have problems, try one by one the following:
File > Settings > Turn off SSL Verification
File > Settings > Turn off "Automatically follow redirects"
I'm working in a virtual server on my 64bits windows 7 machine, and a few weeks this error start to appear on google chrome:
XAMPP: your connection is not private NET::ERR_CERT_AUTHORITY_INVALID
I've migrated to Opera to continue developing on my virtualhost, but today this error started to appear on Opera too.
i've searched on web and only answer i've had is:
Browsers are not accepting auto assigned certify anymore...
Anyone know how to bypass this validation on xampp virtualserver?
Just an update. In Chrome and Vivaldi insert chrome://flags/#allow-insecure-localhost into the address bar and then enable "Allow invalid certificates for resources loaded from localhost." Even changing the domain from example.dev to example.test didn't work until I changed the above setting in the browser.
I could fix a similiar issue by using a different host name. I used "website.dev" an got these error in Chrome 63 on Windows7. After changing the C:\Windows\System32\drivers\etc\hosts to "website.test" and the "httpd-vhosts.conf" accordingly, it works.
I had a same issue over my practicing laravel Vhost.
I changed "div" to "test" and typed "website.test" at the address bar, then it failed with the error, "ERR_CERT_AUTHORITY_INVALID". But if I typed "http://website.test" instead of the one I previously did, it worked. Since then it keeps working without "http://". So I think you need to remind windows TCP/IP hosts that your new host name needs a new mapping set.
You just need to change https:// to http://
Good luck, it worked for me
yes,the virtual host is only worked on browser without doing this: chrome://flags/#allow-insecure-localhost into the address bar and then enable "Allow invalid certificates for resources loaded.
Just change this:
changing the domain from example.dev to example.test.
and your virtual host gonna be work.the result is here in the below
I just changed the domain name from WEBSITE_NAME.dev to WEBSITE_NAME.test and it worked like a charm without me having to write "https://". Didn't had to enable insecure-host flag in chrome. It still shows "Not Secure" in the address bar, but works fine in displaying the website.
Google chrome is not able to open page "http://www.google.com/" instead able to open "https://www.google.co.in/" page.It returns "This site can’t be reached" page in response.
Every URL that contains "google.com" in it fails to open each time.
Please provide the solution.
you can try:
https://www.google.com/ncr
"ncr" means NoCountryRedirect.
Try to reset your chrome settings, Thanks.
reset settings chrome
I think it is happening due to some DNS server error. I also faced this issue, sometimes just disabling and re-enabling network adapter does the job and sometimes just changing DNS server to static solve the issue.(I entered 8.8.8.8 and 8.4.4.4 as DNS server)Here you can check the DNS server details
I am able to set the proxy host and port using the preferences menu, but I see no option to set the username/password.
When I browse, I get a message, proxy is refusing connections. I am using squid proxy.
How do I do this?
I had the exact same problem as you had.
And finaly there is no way to add user and password to the default firefox proxy settings, so we need an addon to handle this for us.
In the current version FoxyProxy is doing this without any problems:
https://addons.mozilla.org/en/firefox/addon/foxyproxy-standard/
So try out the Add-On and you will solve this.

Wikrie
Open Firefox.
In the address bar, type about:config. A warning appears.
Click I'll be careful. I promise! A variety of configuration options appears.
In the Filter box, type network.negotiate.
Double-click network.negotiate-auth.allow-proxies to toggle between true and false. The option must be set to false. (It seems counterintuitive, but you set it to false to make it work with the ISA proxy.)
Find the link for detailed understanding https://kb.globalscape.com/KnowledgebaseArticle10522.aspx
Perhaps you must fill the proxy host value with something like the below
username:password#proxy.thing.com
I have problem with blocking sites by hosts.ini .
For example I have defined:
www.todoist.com www.guardian.co.uk
and when I enter in webrowser (FF, Chrome, IE) www.guardian.co.uk it's redirecting me to www.todoist.com
But when I give address www.guardian.co.uk/sport it's redirecting me to www.todoist.com/sport .
Do You know how to manage with this problem ?
Hosts.ini? Did you mean "hosts" from C:\windows\System32\drivers\etc?
The correct format is
127.0.0.1 www.todoist.com www.guardian.co.uk
Or you can replace 127.0.0.1 with any invalid IP address.
Remember that if you need to prevent other users on your computer to visit those sites, if they have Administrator privileges, they can bypass your setting.
