I wanted to study queries, so I installed MariaDB about a week ago and practiced comfortably, but I had no problems until last night, but when I tried to connect this morning, I got an error. I can't connect to the local server at all. I looked at various sites, but I didn't understand well, so I posted a question here for help. If i am familiar with it, I would appreciate it if you could teach me how to solve it. Thank you.
