Intermittent 522: Cloudflare TLS -> Azure LB -> Azure AKS
Our Cloudflare-proxied TLS requests started having intermittent 522 earlier this week, and had to turn off proxying due to failing assets.
These issues all disappear when proxying is turned off or if users hardcode IPs on their local hosts files.
The majority of our ingress logs show response timings of less than 1 second. And peak at 8 seconds, which indicate that there are no performance issues on origin.
We've also gone through the 522 guide, but we cant find anything concerning so far

We initially assumed it was due to a recent maintenance in MEL, but issues persisted even after that window.

or anyone have any experience in between Azure and Cloudflare recently?
