Genieacs simulator

The simulator shows status online in the UI but when summoned shows offline.

check your firewall/network configuration on the PC that run Simulators

Thanks for the reply. What should I be looking for in my configuration?

please check the listening port of your simulator.
from genieacs host, telnet to TCP port of your simulator, if it’s unreachable, then check your firewall config on simulator’s PC whether incoming request to that port is allowed or not.
