Hello @vu2ffw,

welcome again! Your station 3751 seems to have never successfully connected to the SatNOGS Network. Following the previous thread, I see that the client failed with authentication errors. Potentially there is still an issue with the client configuration / API token.

Check with sudo systemctl status satnogs-client to see if the client is running. Then, please share the logs created by sudo journalctl -u satnogs-client.service.

Sincerely,
kerel

PS: Your station is running an older version of the software, but this in itself is not the issue here. Since the new version does not provide major new features and since no update path available except a complete new installation, I suggest to focus on getting the station running with this older version for now.

When using a rtl-sdr, the satnogs_antenna value can’t be GP, this needs to be RX

These are the allowed options:

SoapySDRUtil --probe="driver=rtlsdr"

And offline means it can’t connect to the satnogs network.

Are you able to ping network.satnogs.org and or db.satnogs.org

antenna RX, as Jan said, and driver=rtlsdr no hyphen.

That points to an error in the satnogs_api_token, go to the network dashboard and copy the key again and paste it without extra leading or trailing spaces.
