IP Office SE 11.1.2.2 Onboarding issue

[NYSTECH]

I have a SE at 11.1 FP2 SP2 with 3 Expansion IP500s at remote locations. I was able to onboard the main server using the WebManager and port 7070. However, I can not Onboard the expansion systems. I select them and press onboarding and it just spins. I can access users and HGs and other configurations in the IP500s from Web Manager.
I tried going direct to IP with

https://x.x.x.x:8443/WebMgmtEE/WebManagement.html.

I can get to Webpage but still unable to click Onboarding.
I also tried Chrome, Edge, IP Exploder and Mozilla

Anyone else see this?

Did you try the Manager Application?

IP Office remote service
IP Office certificate check
CLI based call blocking
SCN fallback over PSTN

Yes. Same issue
