How to resolved Server unexpectedly closed network connection error by Raj Gupta



If you are connecting to your instance with Putty and you receive the error "Server unexpectedly closed network connection,"



Then to Resolved this:-

Go to PuTTy options --> Connection
  1. Change the default value for "Seconds between keepalives(0 to turn off)" : from 0 to 600 (10 minutes) -- in my case taking 30 secound That means it sends a "ping" every 30 seconds to prevent the connection from timing out
  2. Check the "Enable TCP_keepalives (SO_KEEPALIVE option)" check box.
  3. Finally save setting for session





In this way issue will resolved.
