What is the name of the domain?
What is the error number?
What is the error message?
522 error
What is the issue you’re encountering
Some users cannot access the page when using incognito mode (sometimes they can)
What steps have you taken to resolve the issue?
I tested it by changing the SSL certificate to a paid one and modifying the Cloudflare options one by one.
What are the steps to reproduce the issue?
You just need to go to the page of the path I specified. However, some people find it works well.
I attached the network contents and a screenshot of /cdn-cgi/trace.
I think it is a certificate-related error because there is no error message from Cloudflare.
