/mtc/event returns success: 0 and no tracking is done behind reverse proxy

Hi

I am just setting up my first mautic instance. I use a reverse proxy via apache to add https while mautic internally uses http.

I noticed i got no tracking and i can see in inspector that /mtc/event returns success: 0

I have looked in the mautic log and in the pho error log and cannot find any hint to why this is.

If anyone can suggest where I should look it would be very appreciated

Kind regards
Jens
