I’m quite puzzled, been working at this for a while.
I have a website setup for MTA-STS validation, which seems to work fine when not proxied by Cloundflare. The minute I turn the proxy status on, it returns a 301 response.

I have other website setup the same way, but this is the only one giving me trouble.
Any suggestions would be greatly appreciated!
