Hmm, you can terminate the SSL connections on a proxy. Some colleagues at work (but at a different location)maintain such a setup (i.e. I never set it up myself) but the relevant search terms are "reverse proxy" and "SSL termination" on that proxy. Only the proxy needs a proper certificate then, but that's where Let's Encrypt helps.
