Cloudflare: Error 1012: Access Denied

Error 1012: Access DeniedWhat it means
Error 1012 means the site owner forbids access based on malicious activity detected from your computer or network. Cloudflare's documentation says the most likely cause is a virus or malware infection on the visitor's computer, which can generate traffic the owner's settings treat as an attack.
For automation, 1012 can also appear when a shared network (an office, a cloud IP previously used for abuse) has a poor reputation. Cloudflare states that it cannot override the security settings the site owner has set for the domain, so the fix sits with you and the owner.
What is not wrong: the site is up, and your request syntax is fine.
What it looks like
Error 1012
Ray ID: 8a1b2c3d4e5f6789
Access deniedWhy it happens
- Malware or a compromised device on your network generating attack-like traffic.
- A shared IP with a history of malicious activity.
- The owner's security settings treat traffic from your network as an attack.
How to fix it
- Update antivirus software and run a full system scan, as Cloudflare recommends.
- Check other devices on the same network for infection.
- Contact the site owner and ask them to allow your IP address.
- Site owners: review Security Events for the IP and decide whether the detection is accurate.
How to stop it recurring
Keep devices patched and scanned, and run automation from clean, dedicated infrastructure rather than shared or previously abused IPs. Site owners: provide a contact path in custom block pages so affected users can reach you, and periodically review which detections produce 1012 so infected networks are not blocked indefinitely after they have been cleaned. If you are blocked on many unrelated Cloudflare sites at once, that pattern points strongly to a problem on your own network.

Retries and timeouts without writing the loop
Autonoly's HTTP Request node and browser steps have per-node retries, timeouts and continue-on-fail, so a transient 429 or 503 can back off instead of failing the run. It has no proxies or IP rotation: if a site blocks automated traffic, that block applies to Autonoly too.
