📝 Description

Hello,

I have the following config,

Heartbeat Interval (Check every 300 seconds)
Retries 0
Heartbeat Retry Interval (Retry every 60 seconds)
Request Timeout (Timeout after 48 seconds)
Resend Notification if Down X times consecutively (Resend every 288 times)

Certificate Expiry Notification -> Checked
Ignore TLS/SSL errors for HTTPS websites -> Unchecked

as I understand I should receive only one notification once a day (for normal alerts it is this way),
but for certificate expiration I receive one down alert every 5 minutes (it happens with version 2.x and old one 1.x).

Do I have something misconfigured?

Is this a bug?

Thanks a lot.
