Sorry - really weird issue - apologies in advance.
iOS latest 10.2
Latest T-Mo carrier update installed (today).
Can't reach FTP and other sync-related sites via cellular data. Works fine over wifi and has worked fine over LTE in the past.
Could be a Digits issue (some sort of virtual network problem??) or a Carrier update issue (they've been disasters in the past) or T-Mo now blocking ports?
How best to resolve?
anybody else seeing this (or not, but using FTP, etc)?
