SSL Error on Custom Domain

Hi there!

I have configured my custom domain by setting up a subdomain that points to glideapps.

I’ts more than 24 hours and the custom domain is not yet kicking in.

Shared with CloudApp

Why can’t I see the subdomain with the glideapp at aat.gosimplydigital.com but instead it goes to the main website gosimplydigital.com or sometimes this error message ERR_SSL_PROTOCOL_ERROR ?

Thank you!
