EHS6 Socket connection problem in North America | Telit Cinterion IoT Developer Community

June 9, 2017 - 10:27am, 3494 views

My java application on EHS6 open the server socket connection on the port 10000 and wait for the client. I can start the socket client from my PC and connect to EHS6 via IPsec-VPN and private IP address . In Germany it works every time correct (2G and 3G). In USA and Canada (almost only 3G) we have sometimes no socket connection, but the Ping to the EHS6 (private IP address) works good. The mobile provider can't help, he say: "The Ping works good, so is the EHS6 available." Any idea what it can be?
