I suspect that my server IP has been blocked. I need your assistance

Developers Workers
1

My server IP is 8.218.240.232. From this server, I can send messages to my Workers via api-gptvip-workers-dev. My Workers are bound to the domain api-chatgptvpn-cn. However, when I try to access my Workers from my server (IP 8.218.240.232) via this domain, I receive a 403 error code. When I switch to other servers (with different IP addresses), I can normally access my Workers through api-chatgptvpn-cn. I would appreciate if a technician could help me resolve this issue. Thank you!（ Please replace “-” with “.”）

Are you seeing anything in your WAF events that shows your request being blocked?

[root@iZj6cg9r90i26krocznp0rZ ~]# curl http-s://api-gptvip-workers-dev
{“detail”:“Api works!”}

The domain obtained through Cloudflare shows up correctly, but when using a custom domain, the correct page cannot be accessed.（ Please replace “-” with “.”）

[root@iZj6cg9r90i26krocznp0rZ ~]# curl http-s://api-chatgptvpn-cn

Other servers can access it normally, but I cannot access it from my server (IP 8.218.240.232) . The error code is 403, “Just a moment…”. When accessing the domain provided by Workers, api-gptvip-workers-dev, on my server, it works fine. However, I cannot access my own domain.

Did you check this yet @viphoulongzhen?

This is likely Cloudflare Bot Protection or some other Cloudflare service screening your request. If you check your WAF events, you’ll probably see the request getting challenged or blocked.

I have figured out the reason. The ‘Bot Fight Mode’ was enabled and causing the block. Just disable it, and everything will be fine.Thanks！
