Hello all,

I’m trying to have:
(1) *.domain.com in server xx.xxx.xx.1 on apache
(2) domain.com in server xx.xxx.xx.2 on apache

both servers has SSL certificate:
(1) xx.xxx.xx.1 as wildcard certificate.
(2) xx.xxx.xx.2 as let’s encrypt certificate.

After changing the A record for server (2) to point to server xx.xxx.xx.2, I’m facing these errors in server (1):

  1. (net::err _ cert _ common _ name _ invalid)
  2. php warning: file _ get _ contents(): peer certificate cn=`domain.com’ did not match expected

my VirtualHost configuration for server (1)

<VirtualHost *:443>
ServerAdmin info@domain.com
ServerName domain.com
ServerAlias *.domain.com
DocumentRoot /var/www/html
……
</VirtualHost>

I’m try to have domain.com point to wordpress site in server xx.xxx.xx.2, and all subdomain of *.domain.com to server xx.xxx.xx.1
