The remote server returned an error: (401) Unauthorized. claim is empty when connect with service bus topic connection string in service bus explorer

Hi Team,

   I try to connect service bus topic connection string in service bus explorer.(ServiceBusExplorer-4.0.109) and i am getting below exception.  

Exception: The remote server returned an error: (401) Unauthorized. claim is empty. TrackingId:691fcdf2-5a41-4365-b8e1-91cf29b9ba6a_G10

1. Can we connect the service topic connection string in Service bus explorer? 

2. If not is any possibility there to check the topic connection string valid or not?

Note: when i connect service bus Rootmanager connection string, i can be able to successfully connect and i can be able to view the topics details.

Kindly provide your answer.

Thanks
