Fail to create connection

I stored my application in Synology NAS and installed Web Station, php 7.4 and phpMyAdmin applications in the NAS. When I start the application with http://192.168.x.xxx/<my_db_name>/_lib/prod, I was asked to created the new connection, the DBMS type can only choose MySQL PDO.

I can test the connection sucessfully and then saved. But when I click the Rename Connection, the connection profile is gone. Eventually, I still cannot create the connection. Any step I missed for the creation of the connection?

This sounded like a permission issue, make sure you check the chown or chmod of _lib/prod. I couldn’t remember which file the db info is saved at.
