If telnet on port 8090 is refusing the connection, it sounds like the service may not be running or the nano isn’t in the https://geometryliteonline.io expected mode yet. I’d double-check the device IP first (maybe verify with a ping or scan), and if the LEDs indicate it’s locked, it could be waiting for console/serial access for initial setup rather than telnet.
