topic Jupyter Notebook via SAS Viya - access to CAS Server Denied in SAS Software for Learning Community https://communities.sas.com/t5/SAS-Software-for-Learning/Jupyter-Notebook-via-SAS-Viya-access-to-CAS-Server-Denied/m-p/856907#M947 <P><SPAN>Hello. I would like to ask about a technical issue I am experiencing with SAS. I am trying to access the Jupyter Notebook through SAS Studio (within SAS Viya). I was able to establish the CASUSER library in SAS Studio, but I when I was trying to get access to the CAS Server by using python code in Jupyter Notebook (accessed via SAS Studio), it generated an error code that my access to the CAS Server is denied ("ERROR: Connection failed. Server returned: OAuth authentication failed: Access denied"). Can anyone help me diagnose this issue? Thank you</SPAN></P> Thu, 02 Feb 2023 17:53:34 GMT yulun1989 2023-02-02T17:53:34Z Jupyter Notebook via SAS Viya - access to CAS Server Denied https://communities.sas.com/t5/SAS-Software-for-Learning/Jupyter-Notebook-via-SAS-Viya-access-to-CAS-Server-Denied/m-p/856907#M947 <P><SPAN>Hello.

If yes you should have a jupyter icon in the menu rectangle in the middle bottom. When you are using that option you can see and practice with various sample jupyter notebook files. For instance Python_Machine_Learning_Demo.ipynb .<BR />All steps are explained and documented in these files. Does that help?
