I was able to create and connect OPCUA Gateway and send data from my Windows desktop on Wednesday. Friday Morning (after updates 8/8/2024), it stopped receiving the data. I wiped out everything on my laptop, created a new connector and installed. It never gets activated. It is always saying "pending". I tried a couple of times already. There was a message about history being full, earlier today, but I wiped out those logfiles on my laptop.

The North Service Log file says "Could not create session: Channel can only be used for discovery". South service looks okay.
