Hi,
I think you may have misunderstood how the free tier subscription works on CloudConnexa.
You are not limited to three devices, but rather three concurrent connections.
What you are limited to is 1 device per user profile. And I think that's the issue you are running into.
You can find info on it here:

In my opinion the best workaround for this while continuing to use the free tier access, is to create additional users for each device in your CC admin panel.
Hope you found this helpful.
Regards,
