Solved Rocket.Chat currently not Responding

[applecrusher]

I have been installing various applications on the server and I have been mostly happy with cloudron. However, the one thing that I need is a chat, which is what I like about Rocket.Chat. It either is stuck in this long state of "Starting" or the app eventually shows "app not responsive". How could I debug the issue? Can I remove old docker instances of things on cloudron manually through the server?

Hi there, is there anything showing up in the app logs of the app instance? Rocket.Chat is using the mongodb service, so maybe you can also see if that might be low on memory if Rocket.Chat becomes unresponsive.

Further to remove old container, if you delete an app through the Cloudron dashboard, all containers belonging to it will also be purged. So there won't be any old docker container instances around unless the ones currently managed by Cloudron.

I get the following errors now that I found the logs messages that just keep looping. I guess there is a mongodb vs mongo server mismatch? How would I fix that?

These are the logs until it gets to the loop:

@applecrusher the version mismatch warning is not the issue. Also the initial upserts are normal. So I assume there is some issue later or you can paste some longer logs which do show when the app exactly stops or restarts.

[girish]

Can you check the output of dmesg as well to check if you are getting any OOM crashes?

[applecrusher]

@girish Sorry for the late and no reply. It was a new server with nothing on it, so it was just best for me to spend a couple of minutes and just reinstall everything. That worked. I know it doesn't help solve the problem, but that worked for me.
