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@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,
Hamza

If that x.x.x.x is enough to make sure that this request gets to your
nginx, then your nginx config is probably involved.

If this only started yesterday, then changes since yesterday (or since
your nginx was last restarted before yesterday) are probably most
interesting.

And as a very long shot: if you can "tcpdump" to see that nginx is
sending
one thing, but the client is receiving something else, then you'll want
to look outside nginx at something else interfering with the traffic.

Good luck with it,
