I searched for the Threads that had "Can't Open Data Connections" and none seemed to help. My SmartFTP 4.0 is connected to 2 servers. I was able to connect to my main server earlier in the day until I upgraded my firewall/antivirus - and rebooted. Now blank.
However, the 2nd server connection had no problems. Why kept connection to one and not the other? How could this happen?
What am I doing wrong??
Here's the log of my main server that the connection failed:
