websocket closed every minute about cocalc-docker

Seems to hub is always connected and working but the ws is reconnect, not a big issue but the annoyng "starting" splash, as a workaround, there a way to disable this splash?

Here is using the cocalc on chrome latest without any extension enabled:

Do you have a reasonably minimal sequence of steps that I can use to reproduce the problem?

Hi @williamstein, turns out I think I discovered the root problem.

I'm using the Synology DSM 7.2, very new but old kernel (4.4.302+), the docker engine have some problem with the cocalc and I got this error, why I have so much sure?

• I installed the cocalc in my notebook using multipass (ubuntu 22) with hyper-v on windows 10 via cloud-init
• Using the same docker-compose.yml
• Using the same nginx server and configuration

Worked just fine, I got less latency but I think the major problem is the kernel.

Note:

• Before trying this solution I installed the jupyter desktop with jupyterlab ds docker version on NAS and worked without any error
• I have a vs code server on my NAS with the jupyter extension and worked too (the vs code I use for almost 3 years)

I don't know if make sense to provide Synology constrains support by cocalc, so for now I will move to jupyterlab container but I really like to see this project grow, I will keep the server installed on my NAS with watchtower to automatic update, if you want my help to check the new versions, but let me know.
