Hello NGINX users and devs,

it’s not the first time now, that I have the problem that some images  
are just not loading sometimes (only after a few refreshes, gif images  
in this case) with NGINX as reverse proxy. I haven’t figured out yet  
why, I’ve had this problem with the old 0.x branch a few years ago, even  
with the default config and now I have the same problem with the 1.x  
branch and an advanced config with caching enabled (doesn’t matter if I  
enable or disable it, have already tried that). Has anyone had the same  
problem before or has a clue why that could be?

Greetings

In order to be able to assist you we need the config. Without it it’s  
like  
shooting in the dark.

As I said, I’ve also had this before with the default config. Anyway,  
here you go:
