Why can't one SSL certificate be used for multiple machines?

Here is the situation. I am making changes to an application but I do not have test environment. There is a QA server for the testing team to use, but I would rather test the application on my local machine (deploying changes to that server might interrupt the testers). I have setup the environment on my local machine, but there is a problem.

The application reads data from a third party application. It needs an SSL certificate to connect to the third party.

My question is, why can't I use the SSL certificate from the QA server on my local machine?

I have done a cursory search on Stack Overflow, and to me it seems once the certificate is issued from the CA that any computer could use it. My guess is that I have misunderstood some part of the SSL process.

Can a single SSL certificate be used on multiple servers?

No matter what language you speak, no matter what industry you work in, the answer is still the same: Yes, you can use one SSL certificate for multiple domains on the same server. And, depending on the vendor, you also can use one SSL certificate on multiple servers.

Can I use the same SSL certificate on multiple ports?

Yes, absolutely - those services can both use the same certificate.

Can I use SSL certificate on another server?

Yes, it is possible to transfer SSL certificates used with the domain in one server to another along with the domain. Interestingly, it is possible to transfer the certificates used with your Linux/Apache/nginx servers to a Windows/IIS server and vice versa.

Can a single SSL server certificate cover multiple ports per domain name?

Yes, a single SSL server certificate can cover multiple ports for the same domain name.

The SSL Cert is bound to the actual host name. If you have an SSL cert for "qa.example.com", it won't work on your machine named "dev.example.com".

Perhaps that's the issue you're having.
