522 error with cloudflare proxy. Works fine with DNS-only

What is the name of the domain?

app.ai-sft.dev

What is the error number?

522

What is the issue you’re encountering

Getting 522 error only when enabling cloudflare proxy. Works fine when I change the setting to DNS only (checked from multiple locations in EU).

Please make sure you are using the Full (Strict) SSL mode on Cloudflare.

If that doesn’t help, can you change the record to DNS-Only again?
