looks networking issues client sap soap server. here tips , tricks check connectivity between client , server.

1. use ping , tracert: utilities can used check if client can see server. first try ping basic check if server available on client network. keep in mind network restrict use of ping. secondly try tracert(trace route). utility show list of ip client has travel to server.

2. if both steps above work , can confirm server reachable on network can try telnet sessions client server on port service lives. if can connect don't have network issue if cannot connect have firewall issue between client , server.

in summary:

try ping it. if successful telnet it. if cannot ping try tracert server if successful telnet it.
