Notes

This issue can be reproduced in VS Code: No

[sweet-mentat]

In the browser, it hangs, then says that it cannot reconnect.

[lovetodream]

I have the same issues on a Raspberry Pi 4 with Debian using standard password authentication.

[gbruno16]

Same issues on Termux for Android

[jsjoeio]

@gbruno16 are you able to post reproduction steps? Might help with debugging as I have an Android I can test on.

[gbruno16]

I followed exactly the steps in https://github.com/cdr/code-server/blob/main/docs/install.md#termux on a fresh installation of Termux 0.108.
My device is a Huawei Matepad 10.4 (Android 10). Code server starts but after some seconds it disconnects and gives the same error reported above

[jsjoeio]

Okay, thanks for the notes! Can you try running with code-server --log debug and posting the logs here?

[gbruno16]

I hope this is what you asked for:

[jsjoeio]

Perfect! Exactly what we needed. I've seen this same issue so you're not alone. Thanks for posting the logs! We'll look into this.

[EdgarAlonsoPerez]

Same problem here.
local device: raspberry Pi 3
remote device 1: Ipad (ipadOs 14.4.2)
Browsers that i used to test: Brave (Version 1.23.1 (21.2.24.16)), Safari, Chrome
code-server version: 3.9.2

[jsjoeio]

Hi can you try upgrade to 3.9.3 and letting us know if you're still experiencing the same issue?

Feel free to post in the release discussion as well.

[lovetodream]

The issue is resolved after the update, at least for me. 👍

[sweet-mentat]

I updated, and received these errors in journalctl:

So I updated vscode to 1.55.1-1617808414

Also, code server version 3.9.1 works...
