We recently swapped from a Sonicwall firewall to a Palo alto firewall and had all nat etc updated.
We also had to move the Wing server from one server to another locally because the old was running Server 08. Now on server 2016 Standard. Windows firewall is disabled.
In wing, we are using an implicit connection through port 990.
When I try to connect remotely the connection immediately fails.
Disconnected from server
With Wireshark running on the WingFTP server I can see my connection
Any advice or hints for where I might be going wrong? Have worked at length with a Palo alto specialist consultant, so I believe the issue may be with the server running Wing.
