Backup fails about 50-60% of the time
-
@Nozy Thanks for letting me know about IPv6. Didn't event think whether it's enabled or not, and turns out it is.
Would turning it off have any detrimental effects on Cloudron, do you know? Do I need to be aware of something before switching it off?
-
@bazinga turning off ipv6 should be safe. Do this at interface level instead of server level. See https://superuser.com/questions/575684/how-to-disable-ipv6-on-a-specific-interface-in-linux . That said, I am not sure how it helps here though...
Even though I'm not sure what database this refers to.
The Cloudron 'box' code connects to the local MySQL database. It is losing the connection and/or getting that error from the database in the logs. It's not clear why. Can you also check /var/log/mysql/error.log maybe ?

@joseph I cannot even fathom how switching off IPv6 would help with this issue, but since you're saying that backup task uses MySQL db and connects to it - who knows, maybe IPv6 might have some effect there.
I've checked logs for mysql. There are few of them there zipped and they all are 0 bytes / empty, even on the days when backup task fails.
Backup keeps failing - in the past 4 days it succeeded only once. This is getting really annoying as not having backups for DR is a problem.

@bazinga fwiw, I didn't recommend switching off IPv6. I only said it's safe to switch it off
Unfortunately, given the information, I cannot make out what the issue is. Can you write to support@cloudron.io and we can debug what's going on.

@bazinga I had similar issues in recent days using Contabo Object Storage on a Contabo VPS.
I ended up fixing it all simply switching to a different storage solution, here Hetzner Storage Box through SSHFS, and that solved most of my pains.
If you can, try that and save yourself some time and suffering.
