Intermittent Error 522

I’m new to the community, I would like your help to find a solution to my problem.

I am an Internet Access Provider (Autonomous Internet System).

Problem: Some websites* that are hosted on Cloudflare return Error 522. At certain times I have access, at certain times the site returns this error.

*When I access through my ASN network.

Detail: My DNS can resolve domains. I get an ICMP response for the sites’ IPs in both situations: When I have access (NO error 522) and when I do not have access (With Error 522).

Does anyone suggest me how to solve this problem?
