Time synchronization

This issue happens when error messages such as 'recvWindow' must be less than ... appear.
Open an administrator terminal (Win + X then A) and type:
net stop w32time
net start w32time
w32tm /resync
w32tm /query /status

Another solution found by @alpi on discord channel:

OctoBot freeze

When running OctoBot on Windows, clicking into the OctoBot terminal (Powershell or Cmd) can freeze the log output and therefore freeze OctoBot execution (OctoBot will be waiting for the log to be published to continue).
To fix this issue, untick the "QuickEdit Mode" in your terminal properties and restart it.
To open the properties menu, right click on the terminal window header and select "properties".
