The issue you are facing:
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Erase the file /var/log/apache2/nextcloud.access.
This file “nextcloud.access” was in the log’s folder /var/log/apache2, as I was getting errors sending files to nextcloud, and the diagnosis showed that they were the log files that were too big, I decided to delete them.
After that, the server no longer worked.
I can’t send the log files, because I don’t have access to the login, and I still haven’t been able to recover the backup, which will certainly give the same problem of not being able to send files.
Any help will Be great.
Thanks in advance.
