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.
