After updating from TFS 2018 v3 to DevOps Server 2019.0.1 last weekend I now receive this authentication error when attempting to manage security:
TF30063: You are not authorized to access tfs.
I receive this error when attempting to manage security from the Server Administration Console via Application Tier > Administer Security. I also receive the error when I attempt to set permissions via tfssecurity cli tool. I am in the local administrator group and I am listed in the console administration user section.
I'm trying to set permissions because after the update I received several reports from employees that receive errors when they try to access their projects. Those errors are:
TF40049: You do not have licensing rights to access this feature: Code.
*** Edit: Update
This error reoccurred when I upgraded from 2019 to 2020 RC1. The difference is, this upgrade required a migration of the server- since server requirements changed for the new version of DevOps Server.
