Lost ELK connection after new router install

[Blackbird]

I installed a new router and changed the IP address in the "Host" line in ELK PG3 to match the new IP address of the ELK M1XEP.  Now the POLISY keeps showing connected/disconnected repeatedly.  And in ELKRP I have connection issues when connecting to the panel.  If I change the IP number to something different in PG3 then ELKRP connects fine.  So it seems PG3 is causing the conflict.  I figured this out based on a forum message.

"Here's a brief update on my connection problem with the ELKRP software and my M1XEP. After a very short conversation with the folks at SmartHome, My problem is resolved!

The fix was to go into the ISY Admin console and remove the ELK Configuration values, then save the changes. That did it! My XEP stopped re-booting and I was able to reconnect through the RP software.

Apparently, the ISY kept trying to communicate to the M1XEP and because they were not being nice to each other, the XEP kept re-booting."

In ELK PG3 I got this ELK Notices: "Error:07/27/2023 16:47:36 See log for: ELK Controller: Timeout sending message VN!!!"

In the log I am seeing this:

What can I do to fix this?

Thanks

I think I found my problem.  The port on pg3 was set to 2601.  I set it to 2101 and everything seems to work now.
