1. The problem I’m having:
Hello,
I am trying to host sites on subdomains of mine through Cloudflare. Sometimes routes will respond with 525 before returning a expected response after a few retries. I am extremely confused as to why.
On every curl -vL I’ve tried of a subdomain, it occurs only the first time, and then not the second time.
The error does not occur on the main domain (eldon.zone/eldon.dev).
Thank you,
Eldon
