SU 2018 no internet connection error

[colin]

For your interest, I did go on to post this Known Issue, in the hope people will find the solution quicker:

SketchUp (desktop version) thinks you don't have an Internet connection

Do you have a typo here? Should the file path be SketchUp 2018 (not 2016) Could you also note in your original post that this issue can also affect extensions that require internet access for license activation and other online activities. As a developer, we typically use the command Sketchup.is_online to test whether there is a valid internet connection but the issue mentioned prevents this command from giving the correct result.
