Hello, does Cloudron have the ability to make a backup using the Webdav protocol?
I have a Nextcloud (Hetzner STORAGE SHARE) with a lot of space. And I would like the claudron to download backups to it.
I did not find such an opportunity in the settings.

@girish OK thanks.
I was also able to reproduce this problem on my.demo.cloudron.io

Hello, there is a problem with installing Gem files in the redmine application.
Plugins just don't find them.
I already had a problem with the Agil plugin, but even after updating the plugin version (with official support, the situation has not changed).
A "clean install" of redmine also didn't help.
To dispel my doubts, I checked the instructions indicated in the documentation and also tried to install only "REDMINE CRM PLUGIN" (https://docs.cloudron.io/apps/redmine/) and as it turned out there also the gem files are not installed correctly and the application goes in reboot.

@nebulon Thanks!!!
I followed the recommendations and I managed to fix it.
I tried to do in the application terminal itself.
But it turned out it was necessary to use the server terminal. (feel stupid )
The problem was with the "Unbound" service.

Hello. I had a completely full memory on the server. Therefore, the platform has ceased to start correctly. I scaled the server and added more memory to disk. After that, the platform started working correctly, but the redmine application stopped starting. Recovering from backup, removing plugins did not give any results.
The log shows that there is a problem connecting to https://rubygems.org/
How can I fix this problem

Thanks.

Hi!
After updating to version 1.7.0-1, the application stops running.
There were no problems on version 1.7.0.
The log indicates the problem:
Apr 01 13:37:56 LoadError: cannot load such file -- nokogiri/2.7/nokogiri

@nebulon Thanks for the information.

@nebulon
I tried to install the key. But the server rejects it. Maybe SSH needs to be turned on somewhere else?
(Test server)
Thanks.

I could not migrate the database until I deleted the tables in Cloudron that caused the problem. After that, everything worked out. These tables were repeated in a dump.

@nebulon Thanks, I was able to migrate the database simply by deleting the repeating table .
