We are encountering an issue with a subdomain that has been configured with a proxy enabled on Cloudflare. While attempting to access this subdomain, we have observed intermittent behavior where sometimes it operates correctly, while at other times, it results in a “Connection Timed Out” error or CORS (Cross-Origin Resource Sharing) issues in the inspection section.
Upon further investigation, we have identified that after activating the proxy on Cloudflare, the DNS resolution leads to three Cloudflare IP addresses. It has been noted that when a request is directed to a specific proxy IP (identified as faulty), it consistently leads to a “Connection Timed Out” error. However, the other two IP addresses function correctly.
Your assistance in resolving this matter would be greatly appreciated.
