Hello. On April 27, sites that connect via cloudflare.com stopped working for me I wrote to hosting. They said that the IP address and the certificate were not changed.
They said to write to you in support of cloudflare.com I did not find how to write to cloudflare.com support Therefore, I am writing here.
Sites worked stably through cloudflare.com for 2 months I didn’t change anything. Hosting didn’t change anything either. And the sites stopped working. How to find out what happened and fix it?
