srsUE Retransmission Failed, Authentication Reject.

Issue Description

I am building a setup using the Tutorial srsRAN gNB with srsUE and i managed to get the gnb of srsRAN_Project connected to the core of open5gs, but the srsUE of srsRAN4G tries to connect to the core but it gets rejected after 30 seconds: Retransmission Failed. Stop Retransmission. Authentication Reject.

Setup Details

Setup:
3 PCs Ubuntu 20.04
USRP X310 (gNB)
USRP B200mini (UE)
UHD 4.4.0.0

gnb_files.zip

UE_files.zip

open5gs_core.zip

Expected Behavior

Actual Behaviour

Additional Information

I have tried to connect UERANSIM gnb and UE to the core and it worked without problems. I used the same USIM, that i already registered in the WEBUI. I changed several times the TX_Gain and RX_Gain but the best result that i've got is this.

I hope that you help me solve this.

are you sure you have attached the correct gnb.log, i dont see any sign of a UE attaching in the gnb.log or in the PCAP.

@yagoda Sorry, i think, i have uploaded the wrong logs. Here are new gnb and ue logs. Thanks

Hi @dhiaboujebha , any progress on this issue?

[dhiaboujebha]

We didn't manage to fix this issue on this setup. So we switched to another setup, which worked #269 and now we are facing a new issue #412.
