As of now, Im not having this issue anymore. I really dont know what would have caused this.

Im thinking of setting up an opnsense firewall, not sure if it would help though

Thanks a lot guys, really appreciated for the input. Actually I am using vultr.com now, just made the upgrade of my server with it.

Debugged this with @ZeZaung a bit. Somehow, it was possible to re-run cloudron-setup on the existing install and this reset the database even though the app containers and data were still there. I have made a fix which should hopefully mitigate the problem.

@girish That's awesome, thanks Girish! 🙂 Glad I wasn't crazy hahaha

As I said on the other thread I seem to have managed to install cloudron on Ubuntu 20.04 LTS by following your advice to use ./cloudron-setup --version 5.6.3. I've disabled automatic upgrades and I'll wait a bit to upgrade to version 6.
All is good!

Will lock this thread in favor of the same question about a week ago https://forum.cloudron.io/topic/2677/ability-to-schedule-restart-reboots-updates?_=1592566614617

Just my 2 cents here : like girish said, if you want to run other things besides cloudron, you should install cloudron in a VM.

If you really want to dedicate the whole machine to cloudron, there is really no need to bother with the additional layer of complexity, another OS to keep up to date and such. I would go bare-metal in this case. That's how I've been running cloudron for 2 years, and it's great.

@zedomingues Change the title to include [SOLVED] for now

Is this still an issue? Otherwise I will close this thread.
