I have been using Direct Connection via VPN to connect to multiple hosts located in another city. No issues seen for last one 9 months. Now I'm unable to connect to those PCS using Direct Connection. Nothing has changed in the network or on the machines. The 5650 port is still open on VPN.
Also, Connection using Internet ID still works (but slower).
I have tried uninstalling viewer and hosts, but nothing works. This behavior is same on other machines as well.
Please assists here to figure out what's wrong.
attached hosts and viewer side log snapshots.
Viewer version: 7.1.7.0
Host Version: 7.1.7.0
