Hi,

I was running cqrlog, when I got some trouble with another application. I had to hard reset my PC as shutdown from another console did not have success.

Unfortunately somehow the cqrlog database was damaged. Everytime I try to start cqrlog, I got an error.

Error during connection to database: Server connect failed.


I looked up .config/cqrlog/database/mysql.err but I don't know, how to repair a MYSQL database.

Errors from mysql.err are:

I tried to use mysqlcheck, but it requires a database password. Does anyone have an idea, how to continue ? Thanks for any hints.
