Notes

This issue can be reproduced in VS Code: No

The text was updated successfully, but these errors were encountered:

sweet-mentat · 2021-04-01T15:41:05Z

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

lovetodream · 2021-04-01T16:34:37Z

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

gbruno16 · 2021-04-02T07:16:20Z

Same issues on Termux for Android

jsjoeio · 2021-04-02T16:11:07Z

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

gbruno16 · 2021-04-02T21:53:08Z

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 · 2021-04-02T22:09:40Z

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

gbruno16 · 2021-04-03T09:39:21Z

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 · 2021-04-07T21:38:55Z

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 · 2021-04-08T22:14:35Z

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 · 2021-04-09T11:43:19Z

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

So I updated vscode to 1.55.1-1617808414

Thanks for the logs @sweet-mentat - we'll have to dig into this a bit more.

I'm suspecting on I/O...

code-asher · 2021-05-07T19:14:10Z

Just FYI for the next release we will be toggling websocket compression off by default so hopefully this resolves it for everyone. If not then the problem is something else.

GirlBossRush · 2021-08-05T14:54:48Z

@code-asher @jsjoeio I believe this issue will be resolved in the vscode fork. While it’s currently disabled, zlib compression does appear to work in local testing if the configuration is negotiated by the client.

jsjoeio · 2021-08-05T19:07:02Z

That's awesome to hear!
