3DEXPERIENCE Problem

Hello,

I would like to use 3Dexperience applications (Assembly Design for example).
However, after downloading the launcher and roles for Assembly Design (0 problem at this step) I decide to launch the application.
This is what I get as an error message. (image below)
The translation in english is :

« Connection to PLM1 supplier.
Server connection failed
Connection settings to connect to the server are incorrect or the server is not available: .
Check port, root URI, etc.: .
The app will close »

I hope this problem can be resolved.

In any case, thank you for your attention.
Sincerely,

Edu ​​​​​​​3DEXPERIENCE ​​​​​​​Authentication Error
