What is wrong with this forum's server?

I cleared the app cache yesterday. That actually seemed to help. Doesn't usually.
 
Via the AC forums app, if you click the image icon and try to post it fails every time. It worked for a minute but hasnt for a while. using the paper clip works but I feel like it degrades image quality.
I'm not sure why this error affects some users/models.
 
This just encourages pointless posts, like this one, just to get your post count up!
