I have created a rule to allow portable Free Download Manager on D:\ , yet it doesn't connect. I'm running Windows 10 Firewall Control, also portable, and it's showing FDM blocked alerts from FDM: 'BlockedIPv4 TCP ... Block all outbound connections'. Same result with or without WFC running.
I've allowed thru both Windows Firewall direct and WFC, and still doesn't connect.
I've also had errors trying to connect from CMD, PowerShell, also any app downloads that attempt to connect to download fail. It seems anything not in Programs* wont connect. I've tried resetting all the usual: Winsocks, TCP/IP, netsh, TCP/IP, etc.
All other browsers, etc connect fine.
EDIT: I should add I've reset/restored firewall defaults multiple times.
