I had tried the help topics by changing the password for hosting account. but still no luck.

After searching for Error codes in FileZilla [networking - Filezilla timeout after 20 seconds of inactivity - Super User], I realized something to do with my ISP settings. and After Enabling FTP ALG(Application Level GateWay) Pass through under NAT(Network Address Translation) in ISP modem settings then it worked

This kind of debugging is difficult for Non-Technical guys. I would like to suggest @Admin to add connection issue also to Help/FAQ doc so that it will help beginers.
I know about ALGs and about how horrible they can be. But I would not have imagined that router manufacturers would be so stupid to use them on FTP connections as well.
But thank you so much for sharing your findings, I’ll be sure to add it to the relevant KB article!
