What is the name of the domain?

abramo.cloud

What is the error number?

403

What is the issue you’re encountering

I need to add an IP address to the allowlist that should make a post api call to my worker. The problem I’m having is that cloudflare always returns 403 instead of forwarding the request to my worker. Contacting the customer support of the service they told me that the problem could be the fact that they use the TLS 1.2 security protocol. How can I solve it? Thanks

What is the current SSL/TLS setting?

If you’re seeing a 403 error without Cloudflare branding, this is always returned directly from the origin web server, not Cloudflare, and is generally related to permission rules on your server. The top reasons for this error are:

  1. Permission rules you have set on the origin web server (in the Apache .htaccess for example)
  2. Mod_security rules
  3. IP deny rules. You need to make sure that Cloudflare’s IP ranges :arrow_upper_right: aren’t being blocked

Cloudflare will serve 403 responses if the request violated either a default WAF managed rule enabled for all orange-clouded Cloudflare domains or a WAF managed rule enabled for that particular zone. Read more at WAF Managed Rules.

If you’re seeing a 403 response that contains Cloudflare branding in the response body, this is the HTTP response code returned along with many of our security features:
