FTP issue

Hello,

I am having two Azure virtual machines. Both running Windows OS. I configured the FTP on VM1 and I can assess it from FileZilla and my own written c# code.

But When I try to connect the VM1 FTP from VM2 using my code and/or from FileZilla, I'm getting directory listing error. I can connect to FTP but can not list the files or directory.

I checked it with Active and Passive mode.

Please let me know where I'm doing wrong?

Filezilla message:
