The server requested authentication method unknown to the client [phpmyadmin]
It looks like you are trying to connect to a MySQL server using phpMyAdmin and you are encountering an error message saying that the server requested an authentication method unknown to the client.
This error can occur if the authentication method specified in the MySQL server's configuration file (my.cnf or my.ini) is not supported by phpMyAdmin. To fix this error, you will need to update the authentication method in the server's configuration file to one that is supported by phpMyAdmin.
To do this, open the MySQL server's configuration file in a text editor and look for the [mysqld] section. Then, find the authentication_string option and set its value to a supported authentication method, such as mysql_native_password or sha256_password.
For example:
[mysqld] authentication_string = mysql_native_password
Save the configuration file and restart the MySQL server to apply the changes. Then, try connecting to the server using phpMyAdmin again. The error should now be resolved.
It's also a good idea to check the documentation for phpMyAdmin to make sure you are using a version that is compatible with the authentication method specified in the MySQL server's configuration file.
