filezilla ftp file server not working with microsoft azure

Question

I have installed Filezilla FTP on (Windows 2012 R2 server).

When I try to connect FTP through my local IP (ftp://localhost) it asks for login credentials. Once I enter credentials it connects without any issues but when I try to connect through my domain(ftp://alagu.in) it asks for login credentials. Once I enter credentials it throws an error 425 Can't open data connection for transfer of "/"

Things that I have tried to solve this problem but failed listed below

• changing active mode to passive mode
• adding range of local ports to ports inbound and outbound rules

what am I missing here

Answer 1

In Filezilla server config, under Passive mode settings, select the radio button "Use the following IP" and put in the domain name you're using to access the azure VM. (don't use the IP because they're dynamic).

The 100.76.138.36 IP FZ is trying to use for PASV is an internal IP, so it's not accessible from the outside.
