srsUE can not attached to srsENB/srsEPC #1515
Description
I have installed Ubuntu 22.04 and srsRAN_4G on 2 different devices, one is Raspberry Pi 4, another is ThinkPad-T420, also I have 2 hackRF. I followed the instruction of "LTE Setup Guide", on machine 1 (ThinkPad), I run the command "sudo srsepc" first, then I open another terminal and run "srsenb". On machine 2 (Raspberry), I run the command "srsue", but I can see that UE did not attach on the network.
below is the output after the command on each terminal:

I use the default configuration file to run, but no attach procedure happened, is there any expert here to check and support? I will be appreciated.
