     It is really hard to guess what the problem is without 
    In most situations where I had this issue (OK on WiFi but not OK on 
cell) it turned out to be MTU related.
     I am almost certain that the problem you are seeing is caused by 
broken PMTU.
    See the references below for some insight and possible solutions.
