Hello, I’m completely out of ideas.
For a database migration, I need to access two MariaDB servers with HeidiSQL:
-
one running on synology DSM 6
-
one running on synology DSM 7
The first (old) server has been running flawlessly for years. The new server is configured identically, including the same port forwarding rules.
With HeidiSQL, I cannot connect to the second server (DSM 7) at all. However, from the command line I can connect to it immediately from outside.
I’m completely puzzled.
