I have tried changing my master db user password format to mysql native password. But it is not helping. What should I do to get through this problem?

Since MySQL Server 8.0.11

caching_sha2_password

is used as the default authentication method. Still, you can use the plugin

mysql_native_password

to log in with the old method.
