BST Flashing Window Fix
This happens when the client machine's time is out of sync with BST's server, if the time difference is greater than 5 minutes then the server will not authenticate and get stuck in a loop. To fix this we can resync the time by going through Settings, using powershell/cmd, or using ScreenConnect. This shows how to use the ScreenConnect command function.
1. Right-click machine in screenconnect and select 'Command Toolbox'
2. Should pop right up, select 'Run Command'
3. Verify command output
Verify the fix by opening BST.
