Domain with custom hostname certificate is not allowing redirects

I am trying to 301 redirect a page from a subdomain to a page on my main domain by using a forwarding URL page rule and it is not working.

This domain has a custom hostname certificate and I suspect that is causing the issue. Does anyone have any insight as to how I can redirect from a subdomain with a custom hostname certificate to my main domain?

I need this page - https://info.medcerts.com/ask-a-career-coach to redirect to this page https://medcerts.com/start/ask-a-career-coach but the redirect simply does not happen.

Thanks!
