No external GPU detected. Please try again. My computer is thinkpad T470

The night before, I had successfully used a external GPU to run a program. When I checked the next day, the program was interrupted and prompted the GPU to have a problem. At this point, the "GEFORCE GTX" light of the docking station is off. After that, restart the computer and docking station, the light is on, but the prompt does not detect the external graphics card, please try again. I changed a computer and it is still the same mistake. I guess now that the docking station is broken, but how to decide.
