I'm hosting my own webserver and currently don't use port 80 because my ISP has blocked it. But I found out that my ISP doesn't actually block port 443, so I attempted to use Certbot on my domain with a txt record (DNS 01 Challenge I believe it is called). I followed the guide here, and I tried the manual plugin which seemed to work. the output it gave was promising, unfortunately I have not kept it. There were definitely no error messages and the certificate was generated. However, I'm not sure how I would configure apache to use this certificate (please correct me if my words don't make any sense, this whole thing was mostly a learning experience).
So my question is, how would I configure my website to use HTTPS now that I have a certificate from letsencrypt?
Any help is highly appreciated,
