Hey guys,

I followed this tutorial and it looks like i got things working.

However, one of my applications needs a port to work properly and i had to port forward that to the internet (port 1234)

If port forwarding is enabled, i can use the application and it works. But then i get an "SSL_PROTOCOL_ERROR" if i go to it on a internet browser. It has a landing page to show you it's working.

If i disable port forwarding for that port -- The landing page shows up and i get a connection secured in chrome. However, if i do subdomain.mydomain.com:1234 , i get the SSL Protocol Error and my application doesnt work because it only works on port 1234

Here is my config file
