I can connect to Misty via File Explorer(Windows 10 latest build) and through ADP but for some reason when I enter the IP address into Blockly it briefly says “connecting” then proceeds to revert back to “connect”. Same network, verified IP multiple times, and can connect via other methods listed above without an issue.
The easiest way to know for sure is to open the developer console in your browser and take a look at the error that’s being presented. My guess is that you’ve connected to the website over SSL, which isn’t currently supported. If you remove the ‘s’ from the ‘https’ in the address bar and refresh, the connection should complete normally.
