Here is something from the help article. If you follow these steps you can get SketchUp to check your Intranet as a way to see if you are online:
- Open a File Explorer window.
- Copy and paste this text into the path field in the File Explorer window (replace 20## with your SketchUp version number):
%LocalAppData%\SketchUp\SketchUp 20##\SketchUp\
-
Open the PrivatePreferences.json file with Notepad.
-
Locate the line which looks like this:
"OnlineTestURL": "",
-
Change the " " value to a URL that you can reliably contact without any kind of redirect or Proxy interference. This could even be your company’s Intranet site. For example:
"OnlineTestURL": "http://intranet.mycompany.com",
-
Save the PrivatePreferences.json file.
