My matlab license server is apparently up and running but since last weekend I am getting license errors from the desktop client. None of the license details have changed.

Update: the problem is intermittent. It worked fine on Friday, but not yesterday. Now it works fine again with no configuration changes.

You should contact the administrator for your license (probably someone in your IT department) and ask them for help determining what changed (about your machine, the license server, or something else related to your network) to cause this problem. If working together you cannot determine the cause of the problem and how to resolve it, you and the administrator should contact Technical Support for further assistance. You can contact Support using the Contact Us link in the upper-right corner of this page.

Nothing has changed that I know of. The license server runs on a virtual machine running Linux. I have checked the file system and do not detect any changes.
