Hi @csselo,
Both logs don’t seem to provide the full information on which can act upon. I can only see it’s failed with status 1 which is usually the code on generic errors.
Anyway, what I’ll recommend is to recreate the issue and once you do and MySQL fails to check your journal like so
journalctl -xe
There the full information should be displayed and then we should be able to act further upon.

Hello, all
You can also create a simple bash script to check if MySQL is running and if not to restart it.
#!/bin/bash
# Check if MySQL is running
sudo service mysql status > /dev/null 2>&1
# Restart the MySQL service if it's not running.
if [ $? != 0 ]; then
sudo service mysql restart
fi
Run this script every 5 minutes using a cron job like this one:
*/5 * * * * /home/user/scripts/monitor.sh > /dev/null 2>&1
Hope that this helps! Regards, Alex
