Shipped a machine with an eWON Cosy 131 for remote support, S7-1200 on the machine LAN at 192.168.1.10, Cosy LAN side at 192.168.1.250. Six months in, first support call, and I can't reach it.
eCatcher on my laptop connects, Talk2M shows the Cosy online, green, the tunnel comes up. Ping 192.168.1.10 from the laptop times out, and so does a ping to the Cosy itself over the tunnel. TIA V17 can't find the CPU either.
I updated eCatcher to the current version and rebooted the Cosy remotely from the Talk2M page, it came back online, same thing.
Is it the Cosy firmware? Or does the 1200 need a gateway set, which I'll admit I never checked.
Before the firmware. What's the IP range of the network your laptop is on right now, home or office? ipconfig, the adapter with the default gateway. And does eCatcher show a warning when you connect, a yellow one about the LAN?
