So I’ve been having some issues with site and services running slow through Cloudflare. When using my DDNS, or local IP, everything works fine. I’ve tested the Cloudflare settings a ton, but chalked it up to something with the new NAS. Pages would load, but not always complete. And loading times took much longer than expected.
Just recently I decided to delve into the issue again. I had forgotten that I had upgraded my router along with my NAS. After exhausting all avenues, I found the DDOS protection on the router’s firewall was to blame. Apparently it doesn’t play well with Cloudflare.
Hope this helps someone having similar issues.
