Cannot automatically reconnect when code-server restarts

[zapstar]

• Web Browser: Microsoft Edge/Chrome
• Local OS: MacOS BigSur 11.
• Remote OS: Ubuntu Linux (Linux dev-box 5.4.0-1037-oracle how to start this from google colab? #40-Ubuntu SMP Thu Jan 14 09:19:02 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux)

The service by itself starts up fine. Later on when I try to connect to the remote server I keep seeing this error over and over again in the systemd logs.

Let me know if you need any other logs/information, I'll be happy to provide them for you.

Updated Workaround: Essentially if code-server crashes and recovers you'll have to close your code-server browser window and restart it again in the background.

Hi @zapstar!

Thanks for opening the issue and providing your logs. I'm trying to see how I might be able to reproduce this. So no far, no luck - at least while connecting locally on my laptop (not a remote server).

What I'm using

code-server: v3.8.1
VS Code: v1.51.1
Commit: 41ad0c0

Browser: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.16; rv:86.0) Gecko/20100101 Firefox/86.0

Here are the logs. First I tried regular code-server and then I tried with --link

Is there anything else you can provide or any ideas you have about why this might be happening? We didn't have any major changes in 3.8.1 so I'm trying to think what could have caused it (if anything) 🤔

[zapstar]

Can I enable debug or something like that could help you further. Looks like accessing vscode via browser is killing some process. If you can see it complains about error vscode is not running Error: vscode is not running.

[jsjoeio]

Can I enable debug or something like that could help you further?

Yes! That would be great. You can run

code-server --log debug

There is more info here in our FAQ.

[walterreade]

Ran into the same issue. Also resolved by downgrading to 3.8.0.

• Web Browser: Chrome
• Local OS: MacOS Catalina 10.15.7
• Remote OS: Ubuntu Linux (5.4.0-1036-gcp Evaluate use of pkg to make single-binary server #39-Ubuntu SMP Thu Jan 14 18:41:17 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux)
• Remote Architecture: amd64

[jsjoeio]

@walterreade do you mind running code-server --log debug and pasting the logs here?

[zapstar]

I'm unable to reproduce this on a fresh install. Will be able to install 3.8.1 only over the weekend (I use code-server as my primary daily driver).

Here's how I tried to reproduce it in an isolated environment (although, I failed to reproduce it):

# Download the code-server installer for ubuntu
$ docker run --rm -it -v "${HOME}/Downloads:/downloads" -p 8080:8080 ubuntu bash
# dpkg -i /downloads/code-server*.deb
# code-server --auth none --log debug --bind-addr 0.0.0.0:8080

Trying to connect on localhost:8080 is working fine for now.

[kaaax0815]

I got this error in Docker when having Bad File Permissions

[zapstar]

@kaaax0815 that could be the case as well, I was running the container as root.

[kaaax0815]

@zapstar When running the Container as root that should not happen. I fixed this issue by using USER root in the Dockerfile. But I dont use Code-server on docker. I use caprover reverse proxy to code-server on host

[jsjoeio]

Thanks for trying @zapstar!

Sounds good. I'll leave this open until we hear back from you.

[walterreade]

It's intermittent for me, and I can't isolate when/why it happens.

I appreciate everyone's work here! :-)

[jsjoeio]

Strange 🤔 Could it be an issue with an extension? Can you try disabling your extensions?
