Hi Greg -
Can you give me some more details or tell me where I’m off:
Your device was received and worked fine.
You added modules via the admin interface.
After adding the modules, the device worked fine.
You traveled to the “the site” and the modules disappeared. You were able to connect to the device, but you saw a screen which had a RACHEL banner and said “no modules available”.
You went into the admin interface and deleted existing modules, then re-added modules.
Now you cannot connect to the device at all.
