Dear @vikash,

Can you provide your config?

Dear,
I tried to debug this from RAN side, and i found the solution like i was not providing the correct CIDR for UE allocation in free5GC.conf file, after providing the correct CIDR the problem got resolved.
Thanks for your help.

Do you need to change free5gc.conf file in order to register UE? Is the web portal enough?

Dear @ywang06,
no need to change free5gc.conf file apart from our corresponding ip addresses with cidr value. i think web portal is enough with some modifications like giving some examples such as if IP addresses are of class C then cidr would be /24 etc…

Got it, thank you so much. I think we should add the PGW IP value as well as you shown here. We will try it.
