Occasionally when using IE mode on Microsoft Edge you will run into the “not supported” error on the web interface. This is typically due to enabling IE mode after you are already on the “not supported” URL.
To fix this, you will need to go into the Microsoft Edge settings, and head to the “default browser” page.
On this page, there is an option to add URLs under the “Internet Explorer mode page” section. This will likely already have the “not supported” URL. You will need to delete this URL, and add the normal URL with just the IP address. Be sure to add a “http:// before the IP, or sometimes it will not work”
