I managed to solve the problem of connecting the website with the vpn.
If someone has the same problem, and only you enter the phpmyadmin of vpn and enter the User where ta the Privileges of phpmyadmin
and then Change Privileges
where the company that provided you with phpmyadmin login and password and mark Global Privileges all.
remembering that you have to login and password that they provided you and inside where you put the machine's ip you add your vpn's ip.
If you already have it, check if the Privileges are all in the database. to work.
you can close the topic, people discuss the first message, I don't know English. and it was not my intention.
