@jefftuschool Any errors in the browser console? Other things that may cause problems:

1. Browser extensions
2. Private Mode
3. Firewall

[benz0li]

@JokreeTV Please test with a vanilla browser, meaning no extensions/plugins enabled. (The bitwarden extension is know to cause problems for example)

Cross reference:

• v4.99.3 Memory Leak #7320

@benz0li My Edge and Chrome have no extensions and plugins that is also the reason why I tested it with 4 browsers, with all Chromium Base browsers I have the problem I could still test Opera which is Chromium Base and it will be very safe not go when I install it and test it

[danleepw]

having the same issue. No luck on browser with no extension/plugin enabled. Everything goes back to normal after downgrade back to 4.100.3. Pretty sure that the problem is introduced in version 4.101.1

Have the same issue. When using Amazon Q plugin, the login page can't be loaded. I'm using Windows+Edge, remote env is a x86 Ubuntu.

Before this error, 2 other errors occurred when loading the page:

These 2 files should be provided by the code server but got 404.

Hope these may help.

I have the same problem when I use gemini code assist.

Facing the same issue with Jupyter notebooks. Pinning to 4.100.3 resolves the problem.

[code-asher]

Huh yeah can confirm that Chromium is broken but Firefox works.

I wonder why it appears to be dropping credentials?

Reverting this seems to fix it: microsoft/vscode@a654631

Have not found anything yet on if this is expected.

Workaround:

1. Run curl -fsSL https://code-server.dev/install.sh | sh -s -- --version 4.100.3 to install the previous version.
2. Run sudo reboot now to restart the environment.

Both commands can be run in the code server terminal. After reboot, refresh the web page and it will work.

We are experiencing the same error in our company environment. As @DiscreteTom mentioned, we had to revert back. Will this be fixed? We cannot change our company's browser policies to get this working again.
