I encountered the same error condition after updating Java for Chrome on 1/26/2014. Solved the problem by adding my ISY994i URL to the Java Exception List. But I couldn't find the exception list when I went into Java from Control Panel. The following procedure worked for me:
Start/All Programs/Java/Configure Java
- Click on the Security tab
- Under Exception Site List, see if your ISY99x URL is in the list.
- If not, click "Edit Site List"
- Click "Add"
- Enter your URL in the format "http://[iP Address]:[Port number]"
- Then "OK" out of each dialogue box
Of course, I then got all the requisite warnings the I should not trust the URL (Do you have your mother's permission to do this? ) but, since it's MY UL, I told Java it's OK.
