Hi the connectivity is set to behind firewall since the ip that is configured on the endpoint does not match the ip of the packet source address that the tms receives. This means that there is natting going on somewhere. Communication is http/https.
And since tms is unable to reach it as "reachable on lan" it will turn to no http response.
I'm not saying that this is what is going on but its very likely based on your description. Purge the system from
Tms, Start a wireshark trace on the tms server, add the system, look at what ip the response from the endpoint is coming from. Does it match the endpoint ip?
