I have setup two servers which are able to communicate over internet. The PRTG server is able to connect to the destination server. A MS SQL v2 sensor is setup and runs a query. With the SQLv2.exe Im able to run this fine. Result is as I expected. But within PRTG I receive a connection error. "A network-related or instance-specific error occurred while establishing a connection to SQL Server. "
