# When is a floating license checked back in?

## Question:

If you are here, you may wonder how to check in a borrowed floating license

You are getting a "*No available floating licenses"* error when the previous user closes their nTop session.

You are running into License Unavailable - *"All available nTop licenses are in use at this time"* error

## Answer:

When you **close** all active nTop sessions, you are checking back in the Cloud Floating license you borrowed. You don't have to do anything besides **Close** all the nTop windows. This should be instantaneous, and the license should become available for others in the floating pool to check out.

## Is there an idle license timeout?

During the license status check run every 3 hours, we scan all the checked-out licenses to see if they are being used. In case of **inactivity**, they are checked back in.
