Cannot connect to new server

TeamSpeak Server
1

Hello. I’ve set up a server on my Linux machine and have opened up the following ports on my router for this computer:

9987
30033
2010
10022
10011
41144

I can connect to the server from the hosting computer in the client by navigating to “localhost”. However, when I try to join the server by typing in the nickname, I get this message (from other computers):

Failed to Establish Connection to Teamspeak server

Failed Connection Initialization

I checked the server logs and it shows no errors at all. This is a fresh install of the server and client. Anyone have any ideas of what else I could try/ check?

Thanks in advance.

Try in shell:
UFW ALLOW 9987
UFW ALLOW 30033
UFW ALLOW 10011
…

Thanks for the suggestion. I typed those commands in and they went though. I then stopped and started the server. Unfortunately the issue still persists.

On the hosting computer, connecting to “localhost” works, but trying to connect to the server’s nickname results in the connection error.

I’m sure there are issues with your rules on your router.

Check if ports are opened.

Thank you for this helpful tool. It shows port 9987 is closed, but I double-checked on my router and it shows open :thinking: I also allowed it through the software firewall in Linux. I’m officially stumped lol

There could be a lot of reasons for this. E.g. your ISP could run what is called CG-NAT.
Have you tried connecting from a different machine on the same local network?

7

Yes, all machines on my network give me the same error when I try to connect. I suppose my next step would be to contact the router manufacturer or ISP (or both).

Did you use the local IP to test the connection within your network?

9

No, I used the public IP.

Can you try with the local one just to confirm it is not a problem with the server or its firewall.

I’m not sure if I did this right, but I typed in the computer’s network IP address (10.0.0.xxx) into the “Remote Address” field. Then I entered the port 9987. When I check that, it also shows “closed.”
