We’re checking what could be the cause of this (as you should not need a redirect in the first place) and we’ll update the thread once we have more information.
Thanks for your patience! Could you try clicking on the ‘Force HTTPS’ button in Site settings > Domain management > HTTPS and see if that redirects all traffic from HTTP to HTTPS automatically without the need for redirect rules?
Hey @Audrey: my understanding is this setups HSTS, yes? There are some other reasons we don’t quite want to do that yet. If my understanding is wrong on the HSTS, let me know!
Hey @chexton :We were troubleshooting this as a team just now and have enabled the force SSL flag on the site. We’ve confirmed that HSTS headers were not set on the custom domains. Please let us know if you do see any issues and would like us to roll back the flag!
