Hello everyone,
we have upgraded a DMS from DataMiner-10.4.4.0-14113 to DataMiner-10.5.0.0-15579.

Now all servers in the cluster show an Error: Thread problem in SLASPConnection.exe: Handle Notifications Thread

SLASPConnection Log shows:

What am I missing here?

Please note, we have currently an issue that the NATS Ports 4222,6222 and 9090 are not available between the DMAs and are working on it. However that was not an issue in 10.4 and so far we did not notice anything wrong, other than the error messages in 10.5.

Best Regards,
Robert
