If you are trying to access WebJobs logs via a URL with .scm. in it
https://XXX.scm.azurewebsites.net/azurejobsyou may run into an error
"401 - Unauthorized: Access is denied due to invalid credentials.You do not have permission to view this directory or page using the credentials that you supplied"
One of the things you can try is to put just User instead of Site/User
