PLMN selection failure, no cells in coverage/Cell selection failure, no cells in coverage

Hello, i am following a guide from Github, deploying a 5G netowrk with different DNNs, on 5 VMs. I separated Uplane from Cplane and UE from gnb. I am able to run gnb without any problem (NG Setup procedure is successful), but UE registration is not. I verified all IPs and MCC MNC from all VMs NFs and still facing this issue. I am always starting gnb first and then the UE.

I have ubuntu 20.04 and mongo 4.4.15, NAT network on 10.0.2.xx and port forwarding for ssh with putty.

What can i do in this scenario? I am at second attempt to build this network, first time followed another guide, and now i'm facing the same issue.

The guide i followed today: https://github.com/s5uishida/open5gs_5gc_ueransim_sample_config?tab=readme-ov-file
