Error 522 help needed

Getting an Error 522 that I cannot seem to resolve. I checked and it does not appear my firewall is blocking the request. Paid domain through Cloudflare.
It was working fine and I believe after a power outage it never worked the same.
I’m using the domain for Home Assistant on a VM from ESXI 7.0

Any assistants would be grateful.

Thank you

For how long did it work? Longer than some days, or less than 1 day?

Since you mentioned “Home Assistant” I assume this is running at your home on a residential IP? If so, they do change at a reconnect (which also occurs at a power-outage) and therefore you should set up a DDNS script which automatically updates the IP/CNAME at Cloudflare for the correct DNS entry.
