upload error

Uploads of images or gifs in main chat roomwill seemingly fail at random, presenting the same error message every time. Sometimes they will upload just fine, sometimes they instantly fail. It does not seem to effect any specific images or gifs. Uploads work just fine in private messages.

It seems I can drop or view a couple pics.... then I can't do either. Upload error unknown reason or can't view a pic. Then screen freezes or automatically drops my connection. Someone else has same issues, What's up? What's the fix?
