Newbie question : wordpress returning http CSP errors :-(

Hi All,
I have installed a nextcloud and wordpress servers behind a newly installed HAproxy ssl reverse proxy.

My nextcloud server works great ( but I get CSP (Content Security Policy) errors with my wordpress website (
I am sure this is a config problem that I need to fix.
Would you be kind enough to advise on the problem.
Thanks in advance for your help.

Typical SSL offloading problem.
You may need to set a x-forwarded-proto or the like header to tell WordPress that client is using SSL even if itself gets traffic over http.

Je rentre chez moi et je teste.

Merci Baptiste !
