Short summary of what can fix this issue. Worked for me.

1. Azure VM - Firewall

   1.1) Open Inbound port 21

   1.2) Open few Inbound ports for Passive mode - Say 1035 to 1040

2. Azure VM - FileZilla Server

   2.1) In settings - Change Passive ports to 1035 to 1040 ( or what ever ports you opened in 1.2 above )

   2.2) For "External Server IP" option, use "Retrieve external IP address from"

3. Azure Control Panel - Endpoints

   3.1) Open port 21, and 1035 to 1040 ( or what ever ports you opened in 1.2 above )
