Hi everyone!
Today, i'm surfing on my forum, and so I'm seeing that every users has that :

The IP adress is local since a update (i don't know when)
and i've noticed that users must login 2 times to be connected...
I'm not an expert but, my construe is that the user connect to server and server connect to the forum... So I don't how to remove that problem...

I just realize that there is already that problem and it was resolved (by wrong search). So, when i did the update, I updated nginx too. So here the post :

So it solved.
