IPv6-only websites are always marked as down

[Wolfizen]

Action: monitoring website from host configuration
Expected result: website is reported as up in Pulseway panel.
Actual result: website is always reported as down in Pulseway panel.

I have a monitored website configured on one of my hosts. Pulseway reports it as down, yet I can confirm that it is accessible from several different computers and networks. If I delete the Pulseway notification about the website, the notification comes back immediately. This site is accessible via IPv6 only. There is only a AAAA record for the host in the DNS. I presume that might be the cause of the problem, as this problem did not occur until I removed the A record for the host.

I've attached my pulseway config (with certain info redacted), DNS record for the host, and curl HEAD output showing that the website is up.
