Check your .htaccess file. Maybe you redirect all your HTTPS to HTTP. Or maybe you accidentally switch HTTPS to HTTP towards your domain registrar or Cloudflare if Cloudflare is installed.
I have a wildcard certificate for domain.com. DNS also have *.domain.com
When I create a new server it creates newdomain.com and www.newdomain.com
It also creates newdomain.domain.com as an extra alias.
That is ment to be able to build the site before the dns is changed.
When the site is ready I will change dns for newdomain.com and get it’s own certificate.
Am I correct when I think the wildcard certificate should cover this temporary address?
Does it work for others?
