Detailed Description

There is not need to instantiate this class in your code. A client will emit an error state via connectError in case an error has happened while establishing a connection.

The error can be caused by the backend itself or by the server rejecting the connection. If case of errors issued by the local backend, they can be ignored by calling the function setIgnoreError() .

class ConnectionStep

Specifies at which step during the connection establishment the error occurred.

Constant
