Why does my microphone volume keep cutting?

My rode nt1 is plugged into a scarlett solo with phantom power on. It used to work fine but now when I plug the interface the mic works for a little then immediately goes extremely low. It sometimes comes back when I leave it for a while but it goes off when I start using it again. Another way I got it to start working is if I put it in front of a standing fan (as in a lot of wind blows on it). But immediately I move it away, it cuts again.
