Error 522 from Cloudflare to AWS ALB

Hi All,

I am experiencing an issue with my Cloudflare CDN setup, specifically with the edge located in Singapore. I’m consistently receiving a 522 error when trying to connect to the AWS ALB through this edge. However, connections from other Cloudflare edge locations are successful in reaching the AWS load balancer.

Any assistance with resolving this matter would be greatly appreciated.

Thanks

A 522 error typically happens when Cloudflare requests to the origin (your webserver) get blocked. Review the suggestions in this Community Tip for troubleshooting ideas.
