I have successful completed the step-by-step guide at: https://blog.roku.com/developer/developer-setup-guide
After the I have opened http://192.168.1.72 in my web browser I am prompted with Basic Authentication dialog box. I enter my username and password which I configured in previous steps. Once dialog box has been submitted my Hisense Roku TV times out. During one such time out I decided to open Chromium (Linux) developer tools and the web page reacted by displaying the message:
"Failed To Check For Software Update"
One another attempt using Firefox (Linux) the developer tools displayed the following error log:
The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol. 192.168.1.72
Loading failed for the <script> with source “http://192.168.1.72/css/global.js”. plugin_install:21:1
Aside from the apparent malformed HTML, it is suprising that the global.js failed to load. What could be the issue? My WiFi signal is excellent and both TV and laptop are only several feet apart and both devices are in same room as router.
Software version: 9.2.0
