I create backups of this site for many years.
But since a couple of weeks the backup failed.

Then a Screen with an error in red is visible.
This is the message:
========================
AJAX Loading Error
HTTP Status: 500 (Internal Server Error)
Internal status: error
XHR ReadyState: 4
Raw server response:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
=========================

I have read a lot about changing the settings in the config.
Of course I have tested a lot of combinations, but the backup still fails.

What can I do to fix this/

Thanks for your reply.
I read some info in the docs about the maximum_execution_time in PHP.ini

So I have contacted my hoster.
They increased the time to 300sec.
After thsat, I have started a new backup and now it is running without errors.

So this ticket can be closed.
