There are several ways to disconnect from a node. Please follow the instructions for the client you are using.
Close the application that you are using to manage the node.
Note 1: As a normal user, you cannot disconnect from nodes whose connections you did not initiate.
Note 2: As a CC Super-User, you can terminate any user's node connection sessions, including those initiated by another CC Super-User, in the Admin Client.
Note 3: As a CC-SG Administrator, you can terminate any user's node connection sessions, except those initiated by a CC Super-User, in the Admin Client.
