Hello. All my wordpress sites that are linked with Cloudflare have this message when publishing a page or an article.
“Failed to publish. You are probably offline.”
From what I tried to create a proxy in the Rest API can solve the problem, but even making a rule in cloudflare point to the IP of the hosting, it continues with this problem.
Please try again to publish a post, then after a couple minutes visit your Cloudflare Dashboard > Security > Events and check the Cloudflare service that is blocking your request. If it’s a WAF rule, you may be able to create a WAF exception.
