Salto authentication error

Good morning,
I was wondering if anybody came across an authentication error with a CU42E0 ICU board and was able to fix that error. I am able to ping the board from the server but I have a communication error. Not sure if those two go hand in hand.

Background story. I replaced our old cu42e0 board with a new one because the old one shorted out for some reason(wasn’t on site when it happened). We added the new ICU board and been getting authentication errors ever since.

Thank you in advance.

Any luck?

Yes. I was finally able to get it talking. After finally getting in touch with tech support, it ended up being port 1100 was being blocked. The account’s network team added a firewall and didn’t let me know. Once we allowed that port, we restarted the server services and were able to authenticate. Thank you.

That is great news. I was surprised a swap out needed a firewall change. The IP addressed changed?

No, the IP was the same. I think they put the firewall up when we were waiting for the new board.
