Intermittant Http Errors with Cloudflare orange cloud proxied dns entries (ERROR 521 & 525)
Hi, I've been having issues with the proxied dns entries specifically within Singapore. I have team members from Philipines, US and India who aer not facing any error messages when acessing our sites.
We have quite a few subdomains running various web servers and some are just static sites using aws s3, but all are giving intermittent errors 521 and some are 525. There's been no DNS changes recently, and the errors were first reported about 5 days ago.
My setup is Cloudflare for ssl and proxying. I'm on Flexible SSL as some of my endpoints do not have ssl certs. I also have turned off Authenticated Origin Pulls and there are no Origin Certificates in my Cloudflare panel as well.
I've checked with aws support to see if they are seeing any issues but they said that there's no traffic blocking on their end and they aren't seeing any errors or issues. Strange thing is, when I'm on a VPN, there's no issues as well for me, only specifically when I'm directly connected.
The same site, when I keep refreshing, will intermittently load fine. Here are some URLs from our domain
https://qr.xctuality.com
https://xctuality.com
https://the-sultans-palace.xctuality.com/
Also, the strange thing is, around Singapore me and my team have tested, some locations on 4G, the sites work fine, and on some locations its throwing errors (white screen on mobile).
Most office networks (our own and our clients, also throw the error intermittantly as well)
Here's some cf-rays that were successful:
cf-ray 8e653a745d22ab9e-SJC-PIG

cf-ray 8e653417cb17ab97-SJC-PIG

and some failures

Any assistance would be greatly appreciated. Thank you!
