SSL

[jodeleit]

Deployed this with docker, but I get an SSL protocol error. A Let's Encrypt Cert is installed. Forwarding port 443 to 3000 does not seem to solve the problem. Any hints? Sorry for this newbie question.

This may not be what you are looking for, but I run haproxy to do my SSL termination. It runs on ports 80 and 443 and proxies for port 3000. People also seem to like https://nginxproxymanager.com/

Using a proxy gives the ability to add extra security to the SSL communication like ACLs for particular paths and cipher lists.

Sample HAProxy config below from https://ssl-config.mozilla.org/#server=haproxy&version=2.1&config=intermediate&openssl=1.1.1k&guideline=5.6
