Hi @tkolb_7784,
If you are hosting on a windows machine, the easiest solution right now is to migrate your server to use IIS and then add an SSL binding to your site. If you do not want to purchase a new certificate and the self-signed certificate is too much work, you can use Let's Encrypt and configure it via winacme.
If you do not want to use IIS, then you will need to use a reverse proxy to handle SSL connections. Any reverse proxy can be used and a pretty simple one to configure is stunnel. Most reverse proxies can also be used with Let's Encrypt.
If you are hosting via Linux (Docker), then you will need to use a reverse proxy to handle SSL connections. We have a documentation page for different Linux-based reverse proxies including an example for setting up NGINX. These reverse proxies also support Let's Encrypt also.
Please let me know if you have any questions.
Thanks,
Rich
