Passive Origin Monitoring no email alert

Hi, I have enabled Passive Origin Monitoring for my domains. My website is proxied to the IP number at my webserver. When I shutdown the webserver the website becomes unreachable but no notification is sent to the specified email address?

Do I forget something to enable?

Best regards,

Robin Schouten

I see the error generated by Cloudflare is 522 and the passive origin monitoring only acts on the error 521 :frowning: I now use Uptimerobot (external product) for monitoring the uptime of my website.
