Plugin WebDav - Port 21

Hello, everyone,

i have discovered a bug in the WebDav plugin.

If I want to connect to a WebDav service via port 21 (e.g. 172.217.168.35:21) it doesn't work.
All other ports work.

Greetings

Hallo alle zusammen,

ich habe (glaube ich) einen Bug entdeckt im WebDav Plugin.

Wenn ich eine Verbindung zu einem WebDav Dienst über den Port 21 (z.B. 172.217.168.35:21) aufbauen möchte funktioniert das nicht.
Alle anderen Ports funktionieren.

WebDAV plugin v2.9 for Total Commander
Total Commander 9.21a


Viele Grüße

It could be a problem with the Windows firewall. Port 21 is normally used for FTP, and the Windows firewall does stateful packet inspection for PORT commands to allow incoming data connections for the FTP data. It probably gets confused when you send HTTP data over FTP.
