There's a post over there where an image I linked to on my site gives a broken link image (gigantic one at that)....
Not sure if it's all related or not.. but same issue happens on the XF site and they use the proxy also... so I'm still trying to trouble shoot on my end.
AFAIK, I'm not blocking any image requests inbound, and what few places I can share direct links to images from my site to using their image share editor icon (surprisingly, a lot of them don't accept the format XF provides it in) seem to work fine.
The weird thing is... the images DO show up when inserting them via the editor.. it's only once you save the post it breaks.
