By default MySQL does not allow connections from remote machines. You will have to enable this. Open command prompt on the machine on which you have installed MySQL. The type in following command to grant the necessary privileges to the user.
GRANT ALL ON YOURDB.* TO 'parkhya_parkhya'@'rws5.my-hosting-panel.com' IDENTIFIED BY 'USER PASSWORD';
You can also GRANT specific privileges to the USER instead of ALL. Please have a look at MySQL Manual[^
I am assuming that
is the FQDN of the machine from where you are trying to establish the connection. You can even use IP Address, if name resolution is not working.
