We're using an external database (MS SQL) for our ScreenConnect, mainly because of performance. It all works fine except when we lose connection to the SQL server (for example when a firewall does a failover). ScreenConnect does not seem to be able to reconnect to the SQL server. We get no error in Windows Event Viewer, only get the error message "Invalid operation. The connection is closed" on the actual website.

Does anyone have any tips to how we can improve the reconnect functionality? Or somehow log the event, so that we can create an alarm?

We are on 6.2 (thinking about updating to 6.4 soon) and ScreenConnect is running on a Windows Server 2012 R2.

So, the root issue here is that since we package our own Database Provider natively we "cheat" and assume that the connection will never be lost and thus don't implement a way to reconnect without restarting the services to renegotiate the connection.

After briefly looking at the code it wasn't super obvious how to implement this within the current architecture but I certainly agree it's something we can handle a bit better even though we don't officially support other providers. With that said I've registered a bug for the topic within our tracker so that we can take a closer look once time/priority allows. I don't have an ETA on when we would be able to implement anything, however.
