Why is phpmyadmin giving a 404 error?

Question

Nginx

Hello! For some reason, after installing Nginx on the server, phpmyadmin began to give an error 404 Not Found
nginx/1.10.2. However, it opens on the Apache port (81). What could be the reason?

Answer 1

And before, what kind of server did phpmyadmin have, apache chtoli? Was there nginx before? What port did it work on before? Is the phpmyadmin config connected to nginx?
