Connect Error MySQL

[DeN elLoco]

Hello! I need help.
I use cPanel for hosting (on GoDaddy) for my website. Last Tursday I made some changes in php-files (nothing related to connection to DB) and upload them on server. Friday morning everything was still OK. But when I wanted to make some new changes on Saturday, I got this error:

Connect Error MySQL.
Access denied for user 'evbkulxan0cv'@'localhost' (using password: YES)

When I try to sign in on cPanel using usual login and password, everything is fine. But when I use the same login and password on phpMyAdmin, I get this error:

mysqli_connect(): (28000/1045): Access denied for user 'cpses_evi5w8e6l5'@'localhost' (using password: YES)
Undefined index: auth_type

This website has already worked for two years and it's first time I have this issue.

Hey there! If you have root access to the machine, the first thing I would check would be to ensure the MySQL connection string still works. I like to check that on the command line by running:

mysql -u username -p

and then enter the MySQL database user's password that is stored in the wp-config file. If that works, I would expect the connection to work well. If not, you can recreate the MySQL user and database connection in cPanel >> MySQL Databases.

If you don't have root access or SSH access to the machine, you will need to speak with your hosting provider or datacenter to have them help you troubleshoot this connection problem.

Normally this error comes up due to a DB access problem, make sure you enter the correct server address, username, and password in your PHP connection file, and also make sure your DB server firewall is not blocking the App server.
