Seems the 5GC is not correctly running. UPF are not running and/or not configured correctly. It's not a srsRAN issue.

henokbfg commented 3 months ago

the setup works with 1 UE. so I don't understand why the 5GC is not running correctly with 3 UEs when it does so with 1 UE. What can I do?

pgawlowicz commented 3 months ago

@henokbfg did you add UE subscriber data into open5gs user database?
