I have set up vsftpd on multiple servers sporadically over the last few years and currently have it running on a live (k)ubuntu server but I can not seem to get it fully configured for my pc so I can access it via my android phone. The configuration is intended to provide ftp access using my user's shell account for authentication. Currently I can access my system fine when Wi-Fi is turned on for my phone, and I attempt to access using my LAN Static IP(my public IP is dynamic). However when I try to use either of my DDNS providers(one I have used for years, one I just created but both are properly authenticating on my router) Domains over wi-fi it errors out claiming one of the following:
Wi-Fi is off - Nope 5 out of 5 bars on Wi-Fi.
The IP is invalid - Nope, if I manually enter my domain in firefox, it claims firefox can not connect to the server but flagfox detects my proper public IP.
Blocked By Firewall - UFW is disabled atm for testing sake.
FTP Server is Down - running "pidof vsftpd" returns a process id, but I have tried restarting(with success) vsftpd for conf tweaks. This conf is identical to the one running on my production server except for log in banner.
Oh and yes I do have a proper port set for port=XXXXX.
