Creating backup does not effect your sql server.

This is the problem maybe , try to not use fancy characters in your password.

Did you try to rebuild your mysq ?
 
that might be correct, this morning came to my mind to change the DB passwords of each site. but I found a whole another issue that I am not able to log on to the DA panel itself. sounds like while I was trouble shooting did something wrong. I tried to change the password
(passwd admin) on my terminal still not login why I am not able to log in

I checked for Err with :
/var/lib/mysql/`hostname`.err
result: -bash: /var/lib/mysql/server.hostname.com.err: Permission denied

Try:
less /var/lib/mysql/server.hostname.com.err
where the server.hostname.com part is replaced by your real hostame. You should then be able to view the content of that file.

That does only change da password (and admins ftp) but not them mysql password.

To change the mysql root pass, you might want to check this:

Thank @Richard G and @Active8 for your great help. Regarding the troubleshooting in the Troubleshooting | Directadmin Docs is what was used early and sounds like I locked myself out. not sure how. now the main issue that I did something my DA panel that is not accepting the password, it with SSH. now, what should I do. I have a backup which i will keep as last resort. that will waste some work that was not backed up. let's try our best and thank you all for the help.
this is what I got from the less /var/lib/mysql/server.hostname.com.err:
