Nginx instance manager service Active: active (exited)

Hi all

I have issue with Nginx instance manage service. I completed deploy my NMS on digital ocean droplet according to officail nginx document. Everything working fine, I am able to manage instance, deploy configuration to Nginx instance and deploy certificate. At the end of the day, I shutdowned my Droplet via digital ocean. Today, I tried turn on my droplet and found the there is problem with my NMS service. I tried restart nms service. The issue still occur. The service status is Active(Exited)
