nothing is listening on tcp 4317, the port is free

when inputing the IP of the host interface instead of 0.0.0.0 the error is different :

(also same error with 127.0.0.1, but that's not useful)

[christophe-activiumid]

I found the bug after reading the code :

centreon-collect/agent/src/config_win.cc

Line 106 in ab623bb

_reverse_connection = get_bool("reverse_connection");

the registry key here is not the same as defined here:

centreon-collect/agent/conf/centagent.reg

Line 16 in ab623bb

"reversed_grpc_streaming":dword:00000000

I don't know where the client to configure that is coded, I could only fine the service code

when creating manually the registry key "reverse_connection" and setting it to DWORD 1, the service is running
