Hi, we have an on-prem extraction server with a working uplink connection and working SAP/JDBC connections running.

When we try adding a new DB connection, we receive this error message:

"Connection test failed, please check the Data Connection's configuration and ensure that the system is running: Extractor responded with an internal error"

This is hard to troubleshoot, since the service is definitely running and working. Any idea on what might have gone wrong here?

I can rule out a port error, as I can force this one by changing the port of an existing DB-connection.

Thanks for your help in advance!
