i have encountered this before. what language/framework are you using for your backend?
normal php
website
It's really weird it's related to Cloudflare, I didn't do anything except add the domain and make it valid, then set up the DNS, But something strange is happening it's always redirecting to HTTPS, even though I disabled it.
that's unfortunate. i've encountered this error with golang when the cloudflare proxy encounters specific timeouts, but i'm sadly not familiar with php
this is because cloudflare proxy, but without proxy it's useless
yes, your backend is throwing a nonstandard error
what do you mean?
exactly what the error says. your server is returning an unknown error.
this error comes, when I enable cloudflare proxy.

you can try running a trace from your account
see if it runs into any rules that might break something, but i'm 99% certain this error is caused by your backend in some way
why that is i do not know
that's weird
