My station has been off for some time, as I moved and I cannot change my location
The receiver location is not set correctly. The server-side MLAT timing calculations depend on knowing your receiver location. Go to your FlightAware “My ADS-B” page and set your location (click the gear icon).

Any thoughts
I see no active sites associated with your user. You need to be feeding data before the site will appear. The last data feed I see dates back to 2018.
Check that you are logged into the FlightAware site as the correct user, and that you have claimed the current installation (or configured it with the feeder ID of your previous site)
