Cloudflare API Endpoint HTTP Error 522

Greetings Cloudflare Community!

I was trying to load few hundreds of ASN access rules to my Cloudflare account IP Rule section using the API last night, and I managed to add around 300 ish then my script stopped working.
Further digging into it I see the API endpoint https://api.cloudflare.com/client/v4 now shows HTTP Error 522 from my home IP (Both IPv4, and IPv6 /64 block). I’m able to view https://api.cloudflare.com/ but not using the actual API.

This makes me wonder if I triggered anything that caused my IP to be blocked by Cloudflare Firewall.
Here’s a sample screenshot:

It’s been 14-18 hours since I received the first error (HTTP 522), and system status does not show anything API related. I also am able to open the page with my T-Mobile 5G, so … anyone have clue what’s going on? Or if there’s something I can do without contacting Cloudflare support?

Thanks in advance!

The timeout is gone! I have no idea what happened but the probable one is Cloudflare blocked me from visiting the API for 24-ish hours?
