Moisture Detected in Charging Port

I have just recently changed my charging port and exactly the next day, as i unplugged my phone, i got the error that moisture has been detected in my charging port. I dont think the port is the problem and neither my cable since i just bought it new and have never used it before. I tried charging in Safe mode however it showed the error once again afterwards. The charging notification also changed from fast charging to cable charging in a matter of seconds each time i plugged it in
