Hi,

I tried to use pfcpsim (0.2.0-dev) with omec BESS-UPF but the pfcpsim is giving time-out error:

/ # pfcpctl service associate
FATA[0005] Error while associating: rpc error: code = Aborted desc = Message: Timeout has expired.

Config:

PFCP POD:

/ # ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

INFO[0000] Server is configured. Remote peer address: 10.0.5.9, N3 interface address: 10.0.3.10

And I confirmed that the bess upf is actually responding to the PFCP association request:
