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

Hey there!

Was the SSL for the apex domain and the wildcard domains issued on the same droplet? If so this will fail. You would need to point the apex domain to server 2 and generate the SSL for it on that droplet. You may also need to reissue the SSL for the wildcard subdomains on server one excluding the apex domain.

Hope it helps! Nate
