What is the error? my server is crashing

This no crash! It’s a wanted shutdown because your server did not reach accounting service.

Make sure you can resolve domain
And open needed ports for accounting See FAQ.

It could be that Cloudflare thinks that your server IP is suspicious.
You can test your IP on Inspect an IP | Project Honey Pot


After this error, my server crashed. these are the last log entries

Yes in this one shows a shutdown and the reason and not a crash.


Since saturday I have same problem with “Error contacting server RESOLVE_ERROR: Host not found (non-authoritative), try again later”. My server was running smoothly for 11 months without any problem and my license is valid till Aprill 26th. I had to reboot my whole dedicated server and afterwards this error started happening and my ts3 server is shutting down every 2 hour. All necessary ports are opened (like I mentioned server was running smoothly for past 11 months). I also checked my ip in mentioned above cloudfare thing and there are no records regarding my IP so I take it as my IP is not blocked by cloudfare. I also updated my server to latest verions.

The host itself is fine.
I guess something on the system or network where server is running on has changed.

Can you even reach the domain (from that machine)?

Hello, sorry for double post but I didn’t got any response for a while.

So if in general the machine can resolve the domain and you are not blocked by Cloudflare then something on the system prevents the server from reaching the domain.

Did you double check the port forwardings? Has a IP changed or was a firewall rule updated or (could be so many things here).

Nope. Nothing was changed, ports was doouble checked. Firewall wasn’t touched since setting up the TS3 server that is why I say it’s very unlikely that something on my server is causing the problem. On the other hand while looking on the forums I’ve found several more topics regarding the same issue as mine and that there was a problem on your side. So it is safe to assume while resolving the problem on your end something might’ve been messed up. I will try to contact sales department to issue new license just in case.

My ts3 server shuts down automatically every 2 hours. I contacted the company but they couldn’t solve it. I have a license Can you tell me the commands I need to send via Putty for my fix?

Your server had a problem with contacting the accounting server from TeamSpeak.
Please make sure, that you can ping the server “” or “”.

The hostname was not able to get resolved, maybe a DNS problem?
This problem was already solved once, please take a look at the post’s above.

Hello everyone,

I hope my title is not misleading. After the day before yesterday and yesterday my server was exposed to very massive attacks, we have massively revised our firewall settings.

This morning I see the following entry in the LOG file:

2023-03-18 01:23:22.516810|ERROR |Accounting | |Error contacting server RESOLVE_ERROR: Host not found (non-authoritative), try again later
2023-03-18 01:23:42.536748|ERROR |Accounting | |Error contacting server RESOLVE_ERROR: Host not found (non-authoritative), try again later

2023-03-18 09:04:01.682958|INFO | | |myTeamSpeak identifier revocation list was downloaded successfully - all related features are activated

Now my question is: is it a general problem with the accounting server (which wouldn’t be the first time) or is it because of my firewall settings?

Port 2008 TCP is released and port 443 TCP has just been released. Only the TS runs on this server. Or do I not need 443 at all?

Thank you in advance for your help <3

The problem still exists. Do you also have these entries in the logs since yesterday? I don’t think it’s the firewall, outgoing traffic is allowed and the two ports are released for incoming traffic.

That must be local problem where your machine can not reach accounting.
There are no other reports of accounting not working or that it can’t be reached.

See answers above.
