Hi @Bogle

you can't check that with a browser. A browser caches redirects, sometimes certificates and https. Use online tools:

Checking your domain via https://check-your-website.server-daten.de/?q=grahamrmc.com

Domainname Http-Status redirect Sec. G
http://grahamrmc.com/
12.5.52.50 302 https://grmc-web.grahamrmc.com/ 0.293 E
http://www.grahamrmc.com/
12.5.52.50 302 https://grmc-web.grahamrmc.com/ 0.290 E
https://grahamrmc.com/
12.5.52.50 200 7.317 N
Certificate error: RemoteCertificateNameMismatch
https://www.grahamrmc.com/
12.5.52.50 200 7.074 N
Certificate error: RemoteCertificateNameMismatch
https://grmc-web.grahamrmc.com/ 200 7.230 A

The certificate has only one domain name:

CN=grmc-web.grahamrmc.com
	10.01.2019
	10.04.2019
	grmc-web.grahamrmc.com - 1 entry

So both domain names grahamrmc.com and www.grahamrmc.com are insecure.

But: You have that

so your redirect to grmc-web is wrong. Remove this redirect, this isn't required.

Your fqdn is only visible if you create a redirect.

If your dns entry of www.grahamrmc.com has this ip address, there is no need to redirect to your fqdn.
