If you have [SSL/TLS certificates](/ssl/) managed by Cloudflare, every time a certificate is issued or renewed, a [domain control validation (DCV)](/ssl/edge-certificates/changing-dcv-method/dcv-flow/) must happen. When a certificate is in `pending_validation` state and there are valid DCV tokens in place, some Cloudflare security features such as [custom rules](/waf/custom-rules/) and [Managed Rules](/waf/managed-rules/) will be automatically disabled on specific DCV paths (for example, `/.well-known/pki-validation/` and `/.well-known/acme-challenge/`).

- **High security settings**: The website owner might have set their Cloudflare security settings to a high level, making the filtering of incoming traffic stricter. In this situation, even legitimate users may get blocked or have to solve challenges.

- Security protection against malicious traffic, DDoS attacks, or other threats.

- Excessive requests in a short time (rate limiting).

- Bot-like or automated traffic.

- IP addresses listed on public blocklists, such as [Project Honey Pot](https://projecthoneypot.org/).

- **Excessive requests**: Cloudflare may block an IP address if it detects an unusually high number of requests in a short period, in which case it will rate limiting subsequent requests. This is a protective measure against potential abuse or attacks.

- **Traffic from malicious bots**: Cloudflare employs bot detection mechanisms to distinguish between legitimate users and automated bots. If traffic from your IP address behaves like traffic from a malicious bot, it could get blocked.

- Contact the site owner, providing details of your actions when the block occurred and the Cloudflare Ray ID displayed at the bottom of the error page.

- Avoid suspicious inputs or automated scripts.

- Check your IP reputation through [Project Honey Pot](https://projecthoneypot.org/).

- **Verify your own website traffic**: Check for abnormal activity. If you manage a website behind Cloudflare, ensure that your site's traffic is legitimate and not triggering security measures inadvertently.

- **Check your IP reputation**: Verify whether your IP address is listed on public blocklists, such as [Project Honey Pot](https://projecthoneypot.org/). If so, take steps to address any issues that may have led to the listing.

- **Adjust your security settings**: If you are a website owner using Cloudflare, consider adjusting security settings to find the right balance between protection and accessibility.

- Adjust security settings to balance protection with accessibility.

- Monitor blocked requests in your Cloudflare dashboard.

- Allowlist trusted IPs or fine-tune WAF/bot rules to reduce false positives.
