Interepl cannot receive the files and see the following error in the log
"connection in requester mode refused: reason="166, Connection failure" / prot.diag="304, Requester identification not allowed (security)

If you have this error "connection in requester mode refused: reason="166, Connection failure" / prot.diag="304, Requester identification not allowed (security)", it means that the value of the Protocol Identifier (remote site) does not match with the value indicate on the remote monitor.

Exemple :

On the Monitor A

Physical Local Site : Protocole Identifier = ITEM-39770
Physical Remote Site : Protocole Identifier = SUN18

On the Monitor B

Physical Local Site : Protocole Identifier = SUN18
Physical Remote Site : Protocole Identifier = ITEM-39770

We did the test at our end.
If we change the name of remote site from SUN18 to SUN19 on the monitor A, we experience the same error.
