Same issues on Termux for Android

gbruno16 on Apr 2, 2021

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.

I’m getting the same issue,

I’m using SBC, Udoo X86 advanced with additional SSD, just on eMMC. CentOS for OS. I’m suspecting on I/O…

Interesting! Thanks for confirming @lovetodream

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

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

EdgarAlonsoPerez on Apr 7, 2021

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.

I hope this is what you asked for:

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

gbruno16 on Apr 2, 2021

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

sweet-mentat on Apr 1, 2021

@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.

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

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