We have a 3 node cluster which is working fine. The problem is with the stats calls. Any of the following calls takes too long to respond (30 to 45 seconds)

GET \_nodes  
GET \_nodes/stats  
GET \_stats

Thanks in advance for any help 🙂

After restarting the cluster servers, the problem was resolved !
