MySQL connection not possible?

I ask this question again, but this time a little more detailed.

The problem:
If I want to join my Minecraft server, which works with MySQL, it takes about 15 seconds for it to connect and display an error. Means I'm connecting and will be kicked after an login time of 15 seconds for an error like this:

[18:07:04] [Application-Thread / ERROR]: java.sql.SQLException: Access denied for user 'freunde' @ 'localhost'

Now there's one way you could think of:

wrong password

But it's not. I copied the password from Config and pasted it into MySQL. On the other hand, you have to say - as strange as it sounds: A day before everything went with exactly the file. I have not changed anything in MySQL or in the Config. Neither do other users because no other users have access.

What have I done so far:

Checked configs
MySQl exported
MySQL imported
MySQL exchanged with MariaDB - whatever went so far
All passwords of the databases set again
Reinstall from the vServer to delete all MySQL data

And no: none of it worked.

Now you probably want to have a MySQL error log, but it doesn't exist.
It's just empty. Little can be done with that. Unfortunately I don't know where the "normal" MySQL log is, otherwise I would like to send it.

Does anyone have any idea what to do? It's probably a very simple mistake on my part, but I just can't figure it out.

Hopefully someone can help me

Why exactly do you need a Mysql database at Minecraft? Does a special plugin use that and if so which one?

I'm sorry for the late reply.

Yes that's what I do. For my server. The plug-in is my own.
