Can not use thunderbolt port on MBP 13 2017 2018 non touchbar

A thunderbolt port on my device cannot be used for charging or using USB C connections. When I plug the digital multiport adapter into that port, i can't charge the mac either. But USB or mouse can work via USB A port (only when there is a charger to USB C port on adapter).

Hi,

It could be possible that your Thunderbolt hardware is something wrong. You'd better check with Apple Diagnostics if it reports error code NDT001 to NDT006.

Thank you! The diagnostic tool did not detect the error. I have reset SMC and it solved!
