you can see the screenshot observium_behind_reverse_proxy.png at https://nxt.pra.rip/s/KMBojmYpHb2Z8KE info with and without : #proxy_pass_header Set-Cookie; #proxy_cookie_path / /; =&gt; give the same result / issue =&gt; no problem with dns , i use views (internal name is the observium server , reverse proxy have an other name, external name observium pointing to reverse proxy, observium server is unknown)

What is wrong in my config ?

thank you for your help
