Sorry if I have put this in the wrong place or should have put the logs in a better format but with the logs I was not sure.

I have a general idea what the logs mean but have no idea how to fix the issue

For logs: I use pastebin and post a link

nextcloud.log might be more relevant here (in /path/to/NCdatadir)
Run sudo ncp-report from terminal will show all the relevant logs and system info.

OK, thanks, and done

After the command as suggested the results can be found at
