Issue Cannot Connect to Remote MySQL

[WyattParker]

Ok before we begin, I'm new to IIS, new to Plesk.

I've got a website built in Visual Studio. I've tested it on a quick IIS install on my home computer and it's able to talk to both databases, one local and one remote.
On the remote server, I installed a Trial of plesk, the site is talking to the local database, but not the remote one. Now, I did do a test using HeidiSQL and am able to connect to the remote database on the webserver, so I know it's not a FireWall issue.
Any tips would be appreciated as I'm lost. Outside of Plesk, site works fine, inside, not so much.

Hi WyattParker,

Could you please provide some technical details? What error did you see when tried to connect to a remote database? Are you try to add a remote database to Plesk or use it in your app directly without Plesk?
