Is trusted SSL communication between local machines on a network possible

My question is: Is it possible to have a computers on a network communicate with commercial SSL certificates ?

I want to have computer A on my network host a website: A Springboot Webserver application I wrote.

I have computer B on the same network also and I want to access a webpage on computer A via HTTPS (SSL).

I have no problems doing self signed certificates.

But I want to use an SSL Certificate from a Certificate Authority like Comodo. I've been trying it with Let's Encrypt free SSL Certificates and I haven't been able to get it to work so far.

Thanks

  • You can only get a certificate from a publicly trusted CA for domain names which are public. If the names you use match this requirement then you can get certificates for these, otherwise not. Once you have the certificates the setup of the certificates for the internal web servers is no different from the setup on external web servers.
