Using a custom SSL certificate with apache2 backend server

Question

I have a domain (let's say toing.com), which has an SSL certificate bound to it only if I use the hosting provided by the same company (let's say Xhost). HOwever, recently I have a backend server at let's say, back.toing.com which needs to connect with the frontend hosted at toing.com, which is hosted with Xhost and thus uses SSL.

The backend, on the other hand is hosted on another server maintained by us with apache running.

The problem is that we unless we give SSL to back.toing.com, the browser would reject requests made from the frontend.

At this point we cannot use another, downloadable SSL certificate.

So I followed this tutorial to add a self-signed certificate to the apache server, but this configuration still blocks requests. I believe this is because the certificates don't match. However, since back.toing.com is SSL enabled, is there anyway I can configure the backend to be able to get requests from the front, except by disabling SSL for both front and back? Thank you in advance for the advice!

Answer 1

You need to get a wildcard cert so that way it uses the same one but for both front and back end.

Where are you getting your SSL cert from? You could also purchase another cert for the secondary server. A self signed cert will not work in this situation. For security reasons, I would set it up like this and not try to jerry rig something together.
