I’m encountering a strange issue where I get a 522 error when trying to access my website that’s behind the Cloudflare proxy. My server is IPv6-only, and I’ve noticed that the issue seems isolated to specific regions: Singapore, Indonesia, and Vietnam.
Here’s a breakdown of what I’ve observed so far:
Affected regions: Singapore, Indonesia, Vietnam (sometimes Indonesia works, but it often fails again)
Working regions: US, Hong Kong, Amsterdam (I tested through VPN and they all work fine)
I've attached statistics from Cloudflare and my own monitoring system that show the regional access patterns.
Does anyone have experience with similar issues or have suggestions for resolving this? Could it be related to Cloudflare’s routing for IPv6 in those regions?
Thanks
