HAProxy on pfsense issue

Hi all

I am running HAProxy fine on pfsense, just one issue - I have a site running on port 80. I have set it up in pfsense so it has a certificate through Acem, and Back end is set to port 80 and SSL Offloading set. However, I can get to the site on 443…but browsing other parts of the site I get an error… the web address switches to HTTP. If I change it to https:// I can get to the page I need.

It’s almost like HAproxy is not forwarding correctly.

is there anything I can check?
