In Firefox, my main browser, I get the following error:
Unable to connect
Firefox can’t establish a connection to the server at 192.168.1.33:8000.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.
I have disabled "https everywhere" type options in the browser by adding 192.168.1.33 to a list of exceptions, as well as any other blocking software that could possibly interfere with it.
