You need to be using version 64 of OWLCMS or later (current is 64.0.3).
That message indicates you are running an older version

For the new version, you may need to set the shared key at the bottom, this will give it to tracker for sure.
For owlcms I will need to double-check. To be sure I typed it in the owlcms app itself and restarted.
This is my entry on my cloud owlcms application

And this is the tracker on the cloud.
