When Cloudflare observes too many attempts to add a domain to Cloudflare, an error is returned:
*Error with Cloudflare request: [1105] This zone is temporarily banned and cannot be added to Cloudflare at this time, please contact Cloudflare Support.*
Before contacting Cloudflare support, wait 3 hours before attempting to re-add the domain to Cloudflare.
I am having the same problem with my newly registered domain. I just bought it and installed it just an hour ago. I usually don’t encounter this problem before with new domains.
I have also tried to add a site from Cloudflare dashboard and got this error message:
You have exceeded the rate limit for adding or deleting zones. Please try again in 1 hour. (Code: 1117)
