In my case all the ressources are loaded under https but the content is blocked saying the script is not secure and it throws tons of line of mixed-content errors like:
Mixed Content: The page at ‘https://hub.domain.com/’ was loaded over HTTPS, but requested an insecure script ‘http://hub.domain.com/_resources/themes/hub/javascript/bootstrap/bootstrap.min.js?m=1679784696’. This request has been blocked; the content must be served over HTTPS.
So it’s served over https, but I need to serve over https, makes not much sense to me “Your car is blue which is beautiful, but your car would look great if it was blue”. A lot of mixed signal.
