From your description I can suggest a few options:
1) Try change your browser;
2) Check out your firewall - it can block reaching the web interface (either temporary disable it or add an exception for the ODE's IP address in your firewall settings).
Hey!
If disabling tiyr firewall enable you to acess it, make sure you update the firmware to the latest version 1.7
There where some windows security updates that blocked the old webpage messages that we fixed.
Also, we recomend using chrome to access the devices webpages.

I'm having an issue when trying to access the web interface for the ODE. It keeps saying TypeError: Load Failed. Not really sure what to do in order to change some settings.
