Reason
- The server you are accessing is protected by Cloudflare.
- Cloudflare detects that your request is not from a regular browser (e.g., it is a script or API client), so it requires JS verification and cookie checks.
- Your program cannot automatically pass this verification, so access is denied.
Solution
At present, there seems to be no solution. Once Cloudflare protection is enabled, it defaults to verifying various security information through JS, which the slicer environment does not support.
Therefore, it is best to connect using the IP address as before.
