code-server --link on Termux fails

[gphg]

OS/Web Information

• Web Browser: Latest stable Opera Desktop
• Local OS: Windows 10 64-bit
• Remote OS: Android 10
• Remote Architecture: aarch64
• code-server --version: 3.11.1 acb5de6

Steps to Reproduce

1. Get code-server installed on Termux by following this docs: https://github.com/cdr/code-server/blob/main/docs/termux.md
2. code-server is installed and it works fine without --link, I managed to run it on same local area desktop web browser via !P address.
3. Stop the program, then rerun it with --link: code-server, the following error shown bellow:

~ $ code-server --link

Expected

It should works normally.

Notes

I tested it on Google Cloud Shell (it's Debian), get installed via install script and get it running normally. Screenshot is below:

I did the similar procedure, but via Termxu's proot-distro, on Alphine distro with no --isolated flag.

It isn't isolated: it has access to host file system, included install Termux's code-server. I skipped the installation on Alpine and just get it running. It works without --link too. Same IP and same port, just different config (eg password; it's new).

Edit: For reason it's unable to access https://cloud.coder.com/latency

Apparently, you should be able to get code-server --link run with termux-chroot from package proot (package resolv-conf may be needed too).

~ $ pwd
/data/data/com.termux/files/home
~ $ termux-chroot
~ $ pwd
/home
~ $ code-server --link

Please note that this code-server is running under proot and has different file system root.

Edit:
The binary is looking for /etc/resolv.conf, in this case there is none. On Termux, there is $PREFIX/etc/resolv.conf.

@gphg Thanks for the detailed notes/investigation! I am guessing since you closed this, you were able to get it working?

[gphg]

@jsjoeio it's working. But if possible, I want to get it run without chroot. I'll have this issues reopen.

For unknown reason, I can't get any GitHub notification. I have no idea.

Ah got it, I'll change the title then.

Weird. I'm guessing you've read the docs and looked at your settings?

FWIW, here is what mine look like:
