I've read a lot of questions and answers which seem exactly the same as mine, but I can't seem to get my setup to work. I have a VM running Apache with only HTTP support at 192.168.2.101:32773. I can access it on my local network as such just fine. I now am ready to expose it through my Apache web server that has Lets Encrypt setup to generate SSL certificates. So I added this to my server conf file:
<VirtualHost *:32773>
ServerName server.com
SSLEngine on
SSLProxyEngine On
SSLCertificateFile /etc/letsencrypt/live/server.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/server.com/privkey.pem
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / http://192.168.2.101:32773/
ProxyPassReverse / http://192.168.2.101:32773/
</VirtualHost>
However, I get an ERR_SSL_PROTOCOL_ERROR when I try to load it up as https://server.com:32773. If I however change my address to http://server.com:32773, it loads just fine. Anything look wrong in this snippet? Thanks!
This is embarrassing... At some point I changed my port forward rules to point 32773 directly to 192.168.2.101 so I could validate that the rules were working at all. The above config worked as soon as I realized I wasn't even sending traffic to my Apache SSL enabled server.
