Cert Expiry integration not working

I have tried to configure the Certificate Expiry with my host name (also tried the IP), but I get a error message “Connection refused when connecting to host”

I have used the hostname of my unifi controller (cloud hosted) and the integration works fine.

Both the working and non-working systems use Let’s Encrypt certs.

Any ideas?

– Update –
I couldn’t see a way to delete this so will just add a note to say I solved it myself. Turns out I hadn’t catered for the required flow to allow the HA server to hairpin via the router/firewall. Once I spotted the missing rule all is now good.
