Hi Team,

Even I am facing this issue with GitHub extension with Visual Studio 2019. I have tried the above workarounds (uninstalling/reverting to previous version etc.) but no luck.

I am able to sign-in successfully to GitHub on my browser but through extension, when I click on 'Sign in with your browser' option, it opens the browser with the below URL and it just keeps loading:
https://github.com/login/oauth/authorize?client_id=a200baed193bb2088a6e&scope=user%2Crepo%2Cgist%2Cwrite%3Apublic_key%2Cread%3Aorg%2Cworkflow&state=cd3677b8-bf82-4d2d-80c2-71fb3ed7cb63

Below is the error captured from Github Extension log:

I have the same problem,

Logs here
extension.log

Solution worked for me 👍

I solved the problem by connecting in Github : Profile/Settings/Developer settings/Personal access tokens
Then revoke all from token access list. Direct url

@mohan023 @techduggu,

@cyounes was able to resolve this by opening Visual Studio as Administrator before logging in, see #2550 (comment)

Any chance you could give this a try?

I'm still facing this issue. Tried most of the suggestions mentioned here.

@mohan023, I'm sorry this didn't fix it. Thanks for trying!

Hi @mohan023 (and @techduggu),

I think the issue you've been seeing might be this #2560 (reported by @osmanager). I've opened a PR that I hope will resolve the problem here #2562.

Could you try installing the artifact from this build:
https://github.com/github/VisualStudio/pull/2562/checks?check_run_id=1309274757

You can find it here:
https://github.com/github/VisualStudio/suites/1400504505/artifacts/23266202

After opening and installing the VSIX, can you let me know if it works any better? Any help confirming this fix would be much appreciated!

@jcansdale I have the same issue as Mohan023 and techduggu. I tried using the link you provided,
https://github.com/github/VisualStudio/suites/1400504505/artifacts/23266202
but I receive a 404 error.

Hi @BHinrichs1966,

Could you try installing the artifact from this link?
https://github.com/github/VisualStudio/runs/1343191255?check_suite_focus=true

@BHinrichs1966,

I am able to install the “production” version of this extension using the VS extension manager. But, not able to install this local copy. My company does have restrictions on our machines. I am not an administrator on my own machine. Could that be causing this to fail?

Yes, that could be causing this to fail. I'll let you know when this fix has been confirmed and a new version has been pushed to production!

Do we have anyone who is not facing this issue anymore?

@mohan023 I'm seeing this again :/

@mohan023, @ttaylor29,

https://github.com/github/VisualStudio/pull/2562/checks?check_run_id=1343191255

@jcansdale Will this work if I just want normal GitHub and not the GitHub Enterprise Server?

@ttaylor29,

If there is an HTTP proxy between you and GitHub, it could make a difference. I'm interested to find out!

@jcansdale I'll try this in a bit at lunch if I can!

@jcansdale How do I implement this?

https://github.com/github/VisualStudio/pull/2562/checks?check_run_id=1343191255

FYI, I just tried it again with Chrome and it fails ; FireFox still works on my work laptop.

Never mind, I found the artifact folder with the GitHub.VisualStudio.vsix

@jcansdale It still failed :-(

• I go to sign in via this:

• Then I get this to show up

Then this shows up:

@jcansdale @mohan023

I might have found it.

put this into Chrome address bar:

chrome://net-internals/#hsts

Then go to the bottom and delete localhost from the Delete domain security policies

Then try to sign into GitHub via VS2019 and it worked!!!

Chrome and Edge are chromium underneath the hood, so that is why it is happening on both!

I think my work puts these settings on from the group policy. I have to do this with using IIS local to run my web application sometimes.

@ttaylor29 I'm glad you figured it out!

I wonder if it treats localhost the same as 127.0.0.1? 🤔
