The problem

If a tesla_fleet.key file is already present from a previous installation, it will not be replaced or overwritten with a new private key that may be generated during a new installation.

If you have this issue, delete the tesla_fleet.key (e.g. using File Editor). Upon a successive attempt of installing Tesla Fleet integration, a new version of the file containing the new private key should be created automatically.
