We have been stocked in registering UE to Free5GC through web portal. We kept on getting errors of Unknown UE by S-TMSI. The UE is able to connected to Amari Call Pro(eNB/gNB) and EPC without any issue. But when we connect free5GC, we have seen the this error. We only use web portal to registered the SIM card information, and didn’t change anything in APN. Should we?
