@apple502j i download&install the release version（1.3.57.0） from official(msi package)，now i got another error:

projects.bundle.js:150 WebSocket connection to 'wss://device-manager.scratch.mit.edu:20110/scratch/ble' failed: Error in connection establishment: net::ERR_SSL_OBSOLETE_VERSION

it seems the wss certificate has some problem with Chrome broswer.

This seems to affect Chrome-family browsers as well as Firefox.

Here is what I have tried.

Laptop 1 - working Windows 10 1809 build 17763.1217/17763.1282 Scratch link 1.3.57.0 Firefox 66.0.5/69.0/72.0.2 (Firefox 78.0.2 NOT working) Edge 44.17763.831.0 HTML 18.17763 Chrome 84.0.4147.89/84.0.4147.105

Laptop 2 - NOT working Windows 10 1909 build 18363.959 Scratch link 1.3.57.0 Firefox 78.0.2 Edge 84.0.522.44 Chrome 84.0.4147.105

Laptop 3 - Working Windows 10 1909 build 18363.959 Scratch link 1.3.57.0 Edge 44.17763.831.0 HTML 18.17763 Chrome 84.0.4147.105 NOT working

It would appear that the issue is related to a Windows update and certain browser versions will not work if they are updated (Firefox 78.0.2 for example) while Edge 44.17763.831.0 HTML 18.17763 will happily work on the same updated version of Windows
