Problems with Carly adapter on Ford Mondeo

Hello everyone, I own a 2002 Ford Mondeo with a gasoline engine and 175,000 km mileage. I have the following problem: The check engine light is on. My Carly adapter is not connecting to the control unit, although the ignition is on. Does anyone have an idea what could be causing this or how I can fix the problem? Thank you in advance!

Check if the OBD-II port is clean and free of debris, as dirt or corrosion can prevent a proper connection. If the port looks fine, try updating the software in your mobile. Let me know how it goes or if you have any further questions!
