I am unable to get this to work.
I have tried using djed's solution, but this still had no effect.
The only error it throws me are error logs from SQL connections.
Code:
L 11/02/2019 - 00:27:32: [SM] Exception reported: Invalid database Handle 0 (error: 4)
L 11/02/2019 - 00:27:32: [SM] Blaming: VPNBlock.smx
L 11/02/2019 - 00:27:32: [SM] Call stack trace:

But OP said it is optional to connect to a database.
