[Error connecting to 3rd party UA server: Exception: session inactive] I am presenting the same symptoms here with a redLion opc connection which keeps faulting out. it connects and disconnect. the comm does not hold steady. Exception: session inactive: id=NodeId{ns=0, id=10001}
Can you provide some logs and possibly get a Wireshark capture?
It looks like after a gap in the notifications received from this server we try to call the ResendData method, which it appears this server doesn't support, and then the server closes the connection.
A Wireshark capture would help to verify this is what's happening before I send you off to RedLion support.
Per this company IT policies we are not allow to have Wireshark on our PCs. However, I have some others redlions that are connected and working fine.
Get an exception for the gateway machine.
And how can we tell the difference without low-level diagnostic tools?
You'll just have to take my analysis at face value then.

Looking at the log screenshot again, I think it might actually be the Republish service the server doesn't support, and it's closing the connection with transport level error message indicating Bad_ServiceUnsupported.
This is even more egregious than not implementing the ResendData method because it's not an optional part of supporting Subscriptions.
Hey Guys so you know, I tried recreating another OPC connection and renamed the old and it seems to be working holding in. Weird!
