Subdomain on another server
 

Hey all,

I am having an issue with trying to get a subdomain with Vbulletin on a seperate server than the main domain is on. The issue is the ssl cert.

The main domain is on a windows server but I want the subdomain to be on one of my Linux servers. Works fine by pointing an a record to the ip but how do I get the ssl to work?

Thanks

I'm not sure that's possible because SSL certificates are built on the ability to verify a key located in a hidden folder in the public_html folder. You might try placing the same key on both servers but I'm not sure if that works or not. I've never tried it.

Typically a proxy is used to deal with these kind of scenarios. The proxy handles all incoming traffic and has the proper certificates in place and then it routes the traffic to the proper host/IP address.

As we are in the days where you can get an SSL for free, just put a separate certificate on each server.

I don't use Linux servers but on Windows, it's stupidly simple - https://certifytheweb.com/

I got it working with LetsEncrypt. i just couldn't get the wildcard to work but the subdomain is fine now.

Thanks for the replies! It is almost like the old days again when people were actually here! :)

Actually that was my next plan. The main site has cloudflare so I was planning on using that for the ssl but it ended up working through the server.

Thanks Dave

It is pretty easy on Linux as well normally.

I don't think this is possible because sub domain's ssl with goes with ssl of main domain thus you can use 2 ssl certs on a same site.
