"Cloudron Error" in dashboard UI

@girish
Thanks!
Not sure if this is related, I started to see this too sometimes, does Cloudron behave like this when the internet connection is not strong? I've never seen this before, prior to the migration. I checked Cloudron logs, it seems related to cronjob? Possibly it may be a potential cause?

I did check:

@Aizat can you look into your browser inspector and see what errors are displayed in the console there? Also some errors should be shown then in the server logs at /home/yellowtent/platformdata/logs/box.log

[girish]

@Aizat I moved this to a new topic, it's not related to SFTP stuff (pretty sure).

@nebulon Hi
ahh it's forked, and once I click it, now I can see your comment
OK, so it does not happen all the time, so I did not check the console just now.

As for

[nebulon]

Since the errors shown in the notifications, it does not look like the general connectivity to your server is having an issue, but the server or some services on it fail to respond timely. This is not straightforwards to figure out, especially if this happens only sometimes.

One common issue is lagging disk I/O which can be measured with for example sudo hdparm -Tt /dev/<your main disk>

Also when this happens, most likely you should see some timeout errors in the box.log.

Further checkout if some daemons like the box service possibly crashing or getting restarted (sometimes due to memory shortage) Those cases should be visible in the dmesg or journalctl --system logs. Also here it is best looked at when it happens again, since otherwise they might be harder to find within the vast amount of other logs.

@nebulon said in "Cloudron Error" in dashboard UI:

journalctl --system

So it happened again just now, I checked the console and immediately tried journalctl --system as you suggested and it showed:

@Aizat Might be better if you can write to us at support@cloudron.io , so we can see what's up. Looks like the box code is crashing on the server side.

[Aizat]

@girish OK!
Also saw a backup failed notification too for the first time ever, yesterday. I'm really not sure what's happening.
I've written to support and let's get on from there. Thanks
