Cannot connect

Using the latest version of Soulseek i get this message;

Port: 55652/tcp CLOSED. Your router and/or Soulseek client needs to be configured correctly.

What can i do?

As for the old version 157 it does not connect, telling me the server is down.

Cheked the port and it said it was open, now closed.

But use to work perfectly up to yesterday.

What should i do?

Please help with either the old on latest version to make it work. Thnak you.
