One-Click Install Wordpress Droplet - Error establishing database connection returns

Hey there, I have been trying to use the One-Click Install Wordpress Droplet for many many years now and every time after a certain while the droplet starts having the same problem. Error establishing a database connection. The MySQL error log is empty, and I have not found the reason for it so far and searching through the questions usually does not yield an answer so far either.

I found that the daily and weekly cron’s sometimes exit with errors apparently and I am not sure whether that might be related to the issue. Since MySQL does not exit with an error and does not show any errors in the logs and is not running when I ssh into the machine, a simple starting the service fixes the issue.

I have solved it in the past by having another cron-job checking whether MySQL is running and start it if not but that’s not clean and I’d love some help to figure out what the actual problem is. CPU, memory, disk and load are nowhere near any limit to have an impact on either cron or MySQL to be affected by it

Any suggestions or experience with how to fix this possibly?

Thank you
