After many research on this issue. i found to reason for this as above.

1. may be your firewall permissions not allow to connect sever.

2. may your socket setting or ip of server is change.

In my case- i restart my server. and remove firewall setting. Its resolved my problem

so please check your sever socket setting, server ip address and firewall permissions.

and also make sure that server with port 5222 (for device and 9090 for browser ) is always enable.
