Unable to build data connection

[Waqass]

nops ...i have figured it out..its my local isp problem...he has misconfigured network that is causing the problem...I tried to connect to my other servers and the same problem whereas I was able to connect them seamlessly previously....I am installing the sentora again and going to try it through net2ftp..

Edit:
yup its working perfectly through net2ftp and through the file manager ELFileManager
