This looks correct. You can also try this using https://demo.traccar.org in the relay as well.
damn, you was right.
why one application is installing with one default http: than another?
i had to delete, reinstall and correct the Relay 2 times before it get connected to manually entered https://demo.traccar.org
after that finally devices (those 2 i manually added into Manager) became green.
