This is really weird. Can you please follow the steps below to get a fresh installation up?
Pull the latest version of all services, with:
$ cd open-balena $ ./scripts/compose pull
Then reset the current deployment (note the following will delete all data, including the database):
$ ./scripts/compose kill $ ./scripts/compose down $ docker volume rm openbalena_s3 openbalena_redis openbalena_db openbalena_registry
Pull the latest open-balena:
$ cd open-balena $ git pull
Run the quickstart again:
