I am trying to run an ftp server app on my galaxy s4 (tmobile) and it starts ok, binds to the wifi address and port 8021, but then I can't connect to it. I tried pinging my internal ip address as well and it's not responding. I also tried running nmap on it and it says All 1000 scanned ports on 192.168.1.102 are filtered. I haven't been able to find any settings or anything - any idea what could be blocking the ports? I have checked the IP both via a ip info sort of app, as well as through my router's connected devices page. Any ideas?
Update: I just tried a different FTP app just to make sure and same thing.
Update: Here's my nmap output:

I am trying to connect to the phone from my windows box via filezilla and running the nmap from my raspberry pi, again on the same wifi network.
I also checked the router's connected devices and the IP address there matches what the phone shows.
