Weird 522 Error Access From SEA to IPv6-only Server
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

I'd tried to turn on and turn off the “Under Attack Mode” and the error was gone🤷♂️
that's an interesting one, all Cloudflare locations should have perfect IPv6 connectivity. Could be something inbetween. If you're on free I bet you're not actually being routed to local locations for Indonesia/Vietnam
I did the pro trial but the same thing happened until I turned on and turned off the under-attack mode
