Can't connect to NextCloud console

[potemkin_ai]

I'm trying to connect to NextCloud console on Cloudron 9.0.15, but that is all I'm getting:

Resources are fine, log messages shows that container exists and doing well.

sudo docker exec -it ebc4eb53c325 /bin/bash

works just fine.

Hello @potemkin_ai

The @nextcloud app itself is working as intended?
Did you try to restart the app once?
Are there any errors in the browser web console when this is happening?

[joseph]

Does this happen only with nextcloud or with other apps too ? Wondering if this is some network error since I think web terminal uses web sockets which is glitchy on some networks .

Also, possible that nextcloud keeps restarting. docker exec will also work for some time and exit in that case.

Only with NextCloud and it seems like was working fine...

Hello @potemkin_ai
Just to make sure, when is the last time this Cloudron Server was restarted?
To ensure that a simple reboot does not fix the issue.

[potemkin_ai]

Hey, James. Quite a while ago. Don't you want to figure out the root cause?
I can and certainly will reboot the server one day.

Hello @potemkin_ai

Since this is a rather unique issue, I assume this has something to do with how Cloudron streams this to the browser.
This can be very hard to debug, and I would like to first ensure that a simple reboot does not solve the issue.
If a reboot solves the issue, I can also deduce that this is some docker network issue and can then look deeper into it.

@potemkin_ai are you seeing anything in the browsers network inspector or console?

@nebulon I do:

and that is happening not only for NextCloud actually, I just didn't notice!
