Servers - Public

Why doesn't my server show up in the list? Why isn't in registering?

As of April 2020, there are various reasons for this, but please see this important note on Central Server limits.

If you are registered OK and you or your friends can't see your server, you may need to wait, or start your client with the --showallservers option and try connecting from there (see this page on how to start your client with a config option).

Servers - Private

I'm running my client on the same machine as my server but I can't connect to it

It's best to connect your client to localhost (or the IP address of the server's machine on your network if it's not the same; note that on MacOS, localhost may not work properly in which case try 127.0.0.1). Do not connect via the sever's public (WAN) address.

What address do I give to people so that they can connect to my server?

This should be your public IP address (find that with Google). Connect your own Jamulus client to your local IP address. Note that your public IP address can change - see the note on "dynamic DNS" in this guide.

What port numbers can I use?

Keep the default UDP ports. The actual default port is documented by the command line. At the time of writing this documentation, the port number is 22124.

Is a private server a direct server without contact to the Jamulus Central Server?

Yes. Please see Server Types

Can I convert my private server to being a public one?

Yes. Simply check the "Make my Server Public" box in the server window and fill out the details. Remember that you also do not need to port forward if you have a public server.

Headless Linux: I have created a server but it is joining the Central Server but I don't want it to.

To enable a private server, do not use the --centralserver (-e) option when starting your server command line.

Nobody can connect to my server - but I'm port forwarding and can connect locally

If you experience problems such as being unable to connect to servers or an empty server list, you may need to ask your ISP to give you a fixed address, if possible. Some ISPs in Europe are using the Address plus Port (A+P) technique to conserve address space. This will break Jamulus for those running servers at home.
