It worked previously, so I have no idea what the problem could be sad

I attached the code that I'm using.

Mojang rate limits on IP so workers can get rate limited easily

CelesteLove•5mo ago

Yeah I know but I changed the IP to another one hosted in my server and I get the same error And the error says cloudflare even when calling external websites that don't use thinkingpug

Cyb3r-Jak3•5mo ago

What do you mean you changed the IP?

CelesteLove•5mo ago

I tried using https://minecraftapi.eufonia.studio/KernelUwU it works anywhere except in the worker And it shows the same error

Cyb3r-Jak3•5mo ago

Do you have Cloudflare in front of yours? If so then it could be your WAF blocking the sub request

CelesteLove•5mo ago

I have it only for the second API But the error is the same for both of them

Cyb3r-Jak3•5mo ago

Unfortunately don’t know then. I might be able to try it out later to see if I have the same issue

CelesteLove•5mo ago

Don't worry, thank you for your help!

Erisa•5mo ago

Possible you're missing a header like User-Agent? Not sure how your proxy works however

CelesteLove•5mo ago

That's an interesting theory yes, I will try that later

conor•2mo ago

@CelesteLove same issue, did setting UA help?

CelesteLove•2mo ago

It didn't, I had to set up a proxy on my own infra, my theory is that mojang blocks cloudflare IPs

Cool thanks
