WSO2 ESB with Apache Load Balancer : Cert does not match for name

Question

I have setup two esb servers (clustered) in different AWS instance, and I'm using Apache LB to do the load balancing part. I can't specify IP of other instance (or even the same instance) as it gives the following security issue which can be found in the apapche error.log But I can use localhost instead of the ip (for the same server) and it work. My apache config is below to the error log. I think I need to add a certificate to the esb's client store. If it is so please guide me how to do that (I tried specifying the IP as CN but no luck). Or else what am I doing wrong here?

Apache config.

<VirtualHost *:443>
 ServerName mgt.esb.wso2.com
 ProxyRequests off
 LogLevel debug
 ProxyPass / https://<pvt_ip>:9443/carbon/ *** I can use localhost here and it work
 ProxyPassReverse / https://<pvt_ip>:9443/carbon/
 SSLEngine On
 SSLCertificateFile /etc/apache2/ssl/mgt.crt
 SSLCertificateKeyFile /etc/apache2/ssl/mgt.key

 SSLProxyVerify none
 SSLProxyCheckPeerCN off
 SSLProxyCheckPeerName off
 SSLProxyCheckPeerExpire off
</VirtualHost>

Answer 1

 SSLProxyCheckPeerCN off
 SSLProxyCheckPeerName off
 SSLProxyCheckPeerExpire off

I added the following configs to apache config file and could resolve the issue, but what it does is, it stops comparing the CN, PeerName or Expiration.
