In our next version 1.4 that will be released in october, this error will be solved.

If you need a solution for this error earlier you might install version 1.3.1. Before you install the new version, you will have to uninstall the currently installed version on your pc.

Versions 1.3 and 1.3.1 are compatible and are able to sync with one another. If you are using a previous version of time cockpit and want to upgrade to 1.3.1 all other devices and users in your account will have to upgrade to 1.3 or 1.3.1 too.
