I have managed to install FHoSS, but when I try to start HSS, i got following errors:

[Thread-24] ERROR de.fhg.fokus.diameter.DiameterPeer.peer.StateMachine  - StateMachine: Peer icscf.mnc001.mcc001.3gppnetwork.org:3869 not responding to connection attempt
[Thread-24] ERROR de.fhg.fokus.diameter.DiameterPeer.peer.StateMachine  - StateMachine: Peer scscf.mnc001.mcc001.3gppnetwork.org:3870 not responding to connection attempt

I have started CSCFs by following commands:

root@ulak-HP-ZBook-15:/opt/OpenIMSCore/FHoSS/deploy# kamailio -f /etc/kamailio/pcscf/kamailio-pcscf.cfg
loading modules under config path: /usr/lib/x86_64-linux-gnu/kamailio/modules

How do I ensure that CSCFs work? And also how can I troubleshoot error that I've faced on FHoSS. I have attached my config files. Any helps will be appreciated.

Best regards,
