T-Mobile Galaxy S8 Moisture Detected In your Charging Port (S8+)

Did you get a new charger, as well? Or are you using the same charger that came with the phone you returned?
 
Ever since the last update I have been getting the message "Moisture Detected in your charging port...please dry to charge" whenever I try to charge. It has happened 3 or 4 times and I have no moisture what so ever. I am able to reboot the phone and then most of the time I can charge. A couple of times it takes a couple of reboots. Has anyone else experienced this issue and is there a fix?

I am having the same problem.
