Hi @allans

you have created a certificate with both domain names ( https://check-your-website.server-daten.de/?q=wpmss.com ):

CN=wpmss.com
	15.05.2019
	13.08.2019
expires in 88 days	
wpmss.com, www.wpmss.com - 2 entries

But only your non-www version uses that certificate, not your www version.

Domainname Http-Status redirect Sec. G
http://wpmss.com/
35.198.176.205 301 https://wpmss.com/ 0.144 A
http://www.wpmss.com/
35.198.176.205 301 https://www.wpmss.com/ 0.067 A

https://wpmss.wpmss-multisite.com/ 200 0.454 N
Certificate error: RemoteCertificateNameMismatch

And you have a redirect to another domain, there is the certificate wrong.

Looks like your vHost doesn’t have a ServerAlias www-yourdomain.

What says

apachectl -S

unfortunately we are not using apachectl, apaache log is normal, no errors
we fixed alias or www issue
why are we getting the redirect 200
wpmss.com is having redirect becuase of wp multisite
multisite main domain has its own certificate though, which we expanded to include subdomains as well? Should be fine though

#4

the same applies to the main site, certificate is valid and existing but the …daten.de says https://www.wpmss-multisite.com/ 35.198.176.205
200

Error - Certificate isn’t trusted, RemoteCertificateNameMismatch

Now there is a new check - https://check-your-website.server-daten.de/?q=wpmss.com - created 17.05.2019 13:37:20.

Now the certificate doesn’t have the www version, instead the other domain:

CN=wpmss.com
	17.05.2019
	15.08.2019
expires in 90 days	
wpmss.com, wpmss.wpmss-multisite.com - 2 entries

You have it defined. Or the wrong vHost is used.

Please:

What says

apachectl -S

First you should fix your vHost configuration then you should fix your certificates. Then the redirects.
