DC Fast Charging not working, port LED red

Yes I tried multiple and different L3 chargers from different locations and brands. Same issue. Has nothing to do with temperature. Scared that this might not be fixable

 

When this happened to me ('23 only a few months old) it wouldn't charge from any source at all and the granny (level 1) charger it came with showed a blinking fault light at the car end. Apparently the socket or wiring harness had a problem. It's probably fixable, but of course you'll need to visit a dealer with a level 3 charger on the property to get it diagnosed, which Hyundai is apparently working toward.

 

I read somewhere that the problem sometimes arises due to the weight of the charger-cable. The plug has to be in the socket completely straight and deep.
