Weird problem with redirects

[Hamza Aboulfeth]

Hello,

I have a weird problem that suddenly appeared on a client's website 
yesterday. We have a redirection from non www to www and sometimes the 
redirection sends somewhere else:

[root at genious33 nginx-1.11.2]# curl -IL -H "host: hespress.com" x.x.x.x

Sometimes it acts as it should sometimes it redirect somewhere else

If you have any clue about what's happening, do help me :)

Thank you,
