Hi, when i run ./run.sh, it shows [ERRO][SMF][App] Failed to setup an association with UPF[127.0.0.8], error:Request Transaction : retry-out.
then i ignore it and use UEransim to establish gnb and ue, gnb is established successfully but ue stuck when sending pdu session establishment requestment.
so i check free5gc, it says
[ERRO][SMF][CTX] In ActivateUpLinkTunnel UPF IP: 127.0.0.8
[ERRO][SMF][CTX] Allocate PDR Error: this upf do not associate with smf
webconsole shows that UE has been conneceted, it seems like the ue is registered in free5gc.
i also use ifconfig to check network cards of UEransim, the tunnel uesimtun0 is not created.
i suspect that there is some mistake in upf/smf settings, but i dont know how to fix it. Any hints/help will be highly appreciated.
