Netty connection timeout on other pc

Question

I wrote server and client on Java using Netty.When i run client on my PC it works just fine. When i am trying to run client on other PC it throws me:

java.net.ConnectException: connection timed out

What is the reason of this?

Answer 1

Check the connection parameters.

• Is the server visible from another client? (try pinging the server from the client).
• Are there any firewalls between? Try switching them off.
• Check the connection string. Make sure you aren't connecting to localhost.
• Check the server configuration. Does it listen on the proper network interface.

If you check everything and it seems OK. Post the network connection code here.

Happy coding :)
