FTP over T-Mobile Connection

We have a client who just swapped out their internet to T-Mobile and now our application has stopped working. They noted this: > Other users of T-Mobile Home (or business) 5G internet have also > reported problems with FTP transfers. > > Several users on forums have reported that FTP will, indeed, work if > you do the following in the FTP client: > > Turn off PASV (Passive) mode and use Active Mode. It may be necessary > to use Port Mode if that's available. Also, there may. be a mode > called EPSV. Use that if available. > > Here's what one use wrote and explained: > > Here's the heart of the T-Mobile Home Internet FTP problem. T-Mobile > Home Internet ISP is IPV6 and my Cox Cable ISP is IPV4. The older PASV > FTP command (the default for at least my CuteFTP program) works > perfectly on Cox Cable ISP but won't work on T-Mobile Home Internet > IPV6. What did work is changing Data connection type in my FTP program > from "Use global settings" to "Use EPSV" > > "So, what's the difference now between EPSV and PASV?
