There are more concurrent users of RStudio Server Pro than your license supports. Please obtain an updated license to continue using the product



You may see this error message occur for your RStudio Workbench/Server Pro instance, as shown below:



This error message is a little bit misleading (we have filed an issue for this to be addressed in a new release). This error message is actually referring to the number of "named users" being more than your license supports.

Typically, a named user is any person who has logged in to RStudio Server Pro within the last year.  However, the list in the admin dashboard only shows recent activity. In 1.4, we have added new admin commands to perform these operations from the command line instead of having to use the GUI. Documentation for these commands can be found in the admin guide.

The user's tab of the admin dashboard provides information on user sessions and shows you which users count against your license. More information on enabling the administrative dashboard can be found here:

One way to resolve the warning message is to lock users. Locking a user removes them as a named user, which will then prevent them from being counted against your license.You can lock users from the administrative dashboard, or via command line (if you are on v1.4.1717-3 or newer). To do this via the command line, you can run the commands below:

To lock users:

sudo rstudio-server lock-user <username>

To unlock users:

sudo rstudio-server unlock-user <username>

Please ensure you also restart the server for the change the take effect:

sudo rstudio-server restart
