Win11 SSH tunnel IPv6 to localhost not sending data

Question

Using Windows 11 to connect to remote ubuntu 22.04 server

Trying to get data from my node.js app (sveltekit)

SSH connected is established, but no data is received.

IPv6 is answering as but communication from ::1:port to localhost:port is not working.

Tried tunneling with Visual Studio Code / putty /mobaxterm.

With IPv4 all is good, but requires to hack ubuntu server and remove localhost for IPv6 with should be a temporary hack

Hello there,

Do you have an error message or Event ID generated?

This issue has already been reported and closed. You can check this thread https:// github.com/microsoft/WSL/issues/674

This can also happen if a firewall blocks port 7000.

When you connect to port 8783 on your local system, that connection is tunneled through your ssh link to the ssh server on server.com. From there, the ssh server makes TCP connection to localhost port 8783 and relays data between the tunneled connection and the connection to the target of the tunnel. In other words, the server software that you were trying to tunnel to isn't running, or else it is running but it's not listening on that port.

Hope this resolves your Query !!
