Hi,

Scenario:

Do a clean NPM setup SSL, Caching enabled etc. - pretty standard stuff
Setup an apache server in the backend
Setup a standard wordpress
Use a Iphone or Mac with "Icloud Private Relay" enabled.

Result:

The site does not load at all, this can be fixed with by adding this in advanced configuration on the site in NPM:

proxy_hide_header Upgrade;

Now the site will load - but wont show any images - however turning of the cache will fix that issue - which is not really optimal since i want to use NPM to lower the load on the backend server.

My question is:

Why does this happen ?
How can it be resolved ?

Notes:

Using another browser without "Icloud private relay" works fine or even just turning it off - but this is not a optimal solution either since you never know what the scenario of the visitor will be.
