Can't connect in client mode for livestreaming with the default login password

Hello,

I am using the ricoh theta X YR. The cam firmware is 2.80.1.

I setup, the cam to client mode. I can ping the cam from my laptop by wifi connection.
I want to connect to the Web API, but when I give the login password, it is not working and I have the response 401 Unauthorized.

I suppose that I have the wrong login password. I tried:

login: THETAXYRNNNNNNNN (N is replaced by figures) or that THETAXYRNNNNNNNN.OSC
pass: NNNNNNNN

I suppose that I don’t have the right password. Can you give me some info on how to setup the password for client mode access ?

Thank you
