MME cannot reach to HSS for 4G call
Hi ,
I am using srsRAN to emulate eNB, UE and open5GS charts. When I try 4G attach, MME throws this error. I wonder if MME is not able to reach HSS. I am using default configuration and I assume MME will try to send it to HSS 'service - open5gs-hss-frdi
I also checked configmap of mme and it seems to pointing out to correct has
ConnectPeer = "hss.localdomain" { ConnectTo = "open5gs-hss-frdi"; TcTimer = 60; TwTimer = 30; No_TLS; Port=3868; };
What could have gone wrong here?
Error I see on MME >

Hi @nitinbhat
Everything you've used are with the default configuration? I'll check it next week.
BR, Álvaro
