Error: common name for wildcard ssl in subdomain

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
