My arduino Uno is not producing 3.3 voltage

Hi
I have Arduino Uno , today I tried to measure the voltage of pin 3.3
I bought digital multimeter and the result was 0.49 - 0.5
is this possible?? or am I doing something wrong?
I tried the 5v pin and the result is correct about 4.96V
what might cause that?

regards

It's very unlikely.

It's hard to say because we don't know what you're doing.
