HttpClient execute keeps giving ConnectTimeoutException

Question

I have this very big bug in my application that I really can\'t seem to solve. Whenever I make a rest call via the following code:

  HttpGet request = new H         


        

Answer 1

Had a similar issue, could be reproduced only when trying to connect using several devices simultaneously and the solution was:

Instance reboot solved problem with connections. (or just need to restart networking service)

(c) My server/instance admin

Also, there are people who experience similar issues and some other solutions worked for them, for instance:

1. Disable tcp_timestamp
2. Disable tcp_tw_reuse & tcp_tw_recycle
3. Enabled vm save mode in Android manifest: android:vmSafeMode="true"
