I am not able to connect to Community Edition and it is showing the device is Disconnected but I have tried by Uninstalling the bot agent and connecting again but it didn't work and it is asking to contact administrator.

I am having the same problem but in my case In progress section there is showing one bot is running in pending execution. The bot is showing pending from yesterday and there is no update although I can't able to kill or stop. Please anyone help me otherwise I can't able to run another task bot.

And If I try to delete my previous device it's showing like below attached Error message.

Please stop the bot agent service and then try deleting device. Kindly also check if any proxy settings or firewall settings are implemented on your machine which may be interfering with the Bot agent functionality,
