Please include the log data, I can't help you otherwise. Logs can be viewed by calling printImapClientDebugLog() before any other methods. Also, which server are you trying to connect to?

It seems like you are trying to select the folder before you are fully authenticated. Make sure to await each command you send to the server. In your case I suspect a missing await in front of client.login(...) or client.authenticate(...)
