When you try to go to a sub site ( https) It loads the main sites Cert. * We have 3 different ssl certs set up with the 3 main domains. * How would we get the server to load the correct cert per site? * People have said if you use different IP’s it can be done, But that’s really all they say – No real Direction or more info then that ; c ( * Thank you for your time, James Tryon Viewing 6 replies - 1 through 6 (of 6 total) * [Joshua Parker](https://wordpress.org/support/users/parkerj/) * (@parkerj) * [14 years, 9 months ago](https://wordpress.org/support/topic/wordpress-multisite-domain-mapping-and-ssl/#post-2272180) * Let me make sure I understand this correctly. So, you have a multisite install with 2 subsites on the same install but each one is using a different IP address? * Thread Starter [easilyamused](https://wordpress.org/support/users/easilyamused/) * (@easilyamused) * [14 years, 9 months ago](https://wordpress.org/support/topic/wordpress-multisite-domain-mapping-and-ssl/#post-2272235) * Hi Joshua, * not Quite. At this point only One public ip. * The Question is how do I have all 3 sites using https with there corresponding mapped domains? * Below is some of the conversation from the hackers mailing list today. * > Each SSL certificate *requires* a unique IP address on the server.

You can’t do that will multisite and mapped domains. Each domain must be hosted on the server (not mapped) and they all must have a dedicated IP. * Thread Starter [easilyamused](https://wordpress.org/support/users/easilyamused/) * (@easilyamused) * [14 years, 9 months ago](https://wordpress.org/support/topic/wordpress-multisite-domain-mapping-and-ssl/#post-2272393) * I found the solution. If you force the domain to IP mapping on the server it allowed the certificates to work properly. * Thanks for all your help * [stoutdesign](https://wordpress.org/support/users/stoutdesign/) * (@stoutdesign) * [14 years, 9 months ago](https://wordpress.org/support/topic/wordpress-multisite-domain-mapping-and-ssl/#post-2272427) * [@easilyamused](https://wordpress.org/support/users/easilyamused/) – Do you mind elaborating just a bit more on your solution? * Thanks in advance * Thread Starter [easilyamused](https://wordpress.org/support/users/easilyamused/) * (@easilyamused) * [14 years, 9 months ago](https://wordpress.org/support/topic/wordpress-multisite-domain-mapping-and-ssl/#post-2272492) * This was a first for my self and the guys running the server. * We both have set up ssl certs on single sites and even multisites with out domain mapping. * This is what The Server Guy(need to get permission to say there company name) Said. * > I added entries in the host record to point back to the server.
