Not connecting to Lego Boost on Windows 10

[ThomasEnzinger]

Expected Behavior

I'm trying to connect the Lego BOOST set for my son to https://scratch.mit.edu/boost.

Actual Behavior

I'm trying to make it work for quite some time now, and actually one time I succeeded. I could control the Lego BOOST motors. So I know my hardware is capable to do the job. But I since then I was not able to make it work again, and the behavior is quite strange: When I click 'Start Searching' I can see the search-window (with the image of the BOOST) for a fraction of a second. Then it immediately changes to the screen which tells me '(1) Make sure you have Scratch Link installed and running (2) Check that Bluetooth is enabled'.

Steps to Reproduce

• Install Scratch Link (I have tried with 1.3.0.0 and with 1.3.10.0)
• Try to add the Lego BOOST extension (https://scratch.mit.edu/projects/editor)

Operating System and Browser

• Windows 10 Pro, Build 18363
• Chrome 80.0.3987.149 and Firefox 74
• Scratch Link 1.3.0.0 and 1.3.10.0

Issues with your own personal setup for a device are best addressed to contact us: https://scratch.mit.edu/contact-us/

However, @ThomasEnzinger it may be worth going into your OS's bluetooth settings and "Forget" the boost and try again. Sometimes your OS prevents Scratch Link from finding the device.
