MySQL Database Error: An existing connection was forcibly closed by the remote host

Hi,

We are using Toad Data Point 5.1 with TIC 5.1 and since recently, we are getting this error when trying to connect to Intelligence Central

"MySQL Database Error: An existing connection was forcibly closed by the remote host"

The server is running fine, all services up, port is open and web portal shows no health issue.

From the server directly, I can connect. So it needs to be on the network side I guess.

Any clue of what I need to check to find the cause? Is there a way I can see more detailed logs on what's happening?

Thanks
