Issues with gohispeed.com O365 hosted Exchange

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

Hi @breitzammer

you use two different certificates ( https://check-your-website.server-daten.de/?q=gohispeed.com ):

Domainname Http-Status redirect Sec. G

Your non-www has an expired certificate:

CN=gohispeed.com
	15.05.2019
	13.08.2019
27 days expired	gohispeed.com - 1 entry

Your www certificate is valid:

CN=www.gohispeed.com
	29.07.2019
	27.10.2019
expires in 48 days	www.gohispeed.com - 1 entry

How did you create these certificates? Without root access?

Easiest solution: Create one certificate with both domain names and use that.

PS: Your www version has mixed content.

The file

has some url("…") definitions:
