I updated my GW 7 Linux system to GW 8. The issue: web console for the
Primary Domain is not longer working.

In the log I found this error:

21:06:24 136 Starting GWHTTP-Listener
21:06:24 568 Error Listen Port is already in use. [856B]

21:06:25 168 Message Transfer over SSL: Disabled
21:06:25 168 TCP Port for HTTP Connections: 7281

21:06:28 568 DIS: Error initializing SOAP: [856B]
21:06:28 568 DIS: SOAP is not enabled

The port 7281 was used at GW 7 and this port is free - verified.

Any ideas how to get the web console working again?
