Hi dear,
You can try checking your rank through your email id. Authorities also send result to you through your email id's too. Some times due to some technical issue like high traffic on website the server gets slow and unable to process your request.
Try refreshing your result page or login again after some time. If problem again persists try contacting examination authorities through their official website.
You can also use Career 360 rank predictor to know your exact ranking.
All the best.
