Transfer channel can't be opened. Reason: The requested address is not valid in its context
Since 3-4 days, I'm not able to connect to an FTP-server anymore. The weird thing is, I can still connect from my local machine, but I can not from my VM (Windows Server 2012 R2). I'm using the same version on both machines which is the newest so far: 5.9.4 (build 7333). Other clients can still connect succesfully, as well locally as on my VM. Some extra details:
I'm using GUI, commander style interface and all default configuration are on since I've reinstalled the newest version of WinSCP once over again. Port 21 for WinSCP is added to the windows firewall like it should. But even after shutting down the firewall, the same error applies.
"Transfer channel can't be opened.
Reason: The requested address is not valid in its context.
Could not retrieve directory listing"
In attachment, I've added the full log file of the VM.
Thank you in advance for your time and effort :)
