Hello @fferraro87 ,

to use the repository you can either use the username “serial” and your subscription key as the password, or you can use the username and password from In both cases your subscription key has to be valid (e.g. not expired) and for the portal account at least one valid subscription has to be linked to the account.

thanks @fbartels
