Accounting not reachable IPtables

Hello everyone,

I have refined my firewall settings. That was also important. Now I have tested everything and almost everything works. Except for one thing: I get the following error in the log

2024-09-25 07:26:28.337685|ERROR |Accounting | |Error contacting server https://accounting2.teamspeak.com: CANCELED
2024-09-25 07:26:28.348488|ERROR |Accounting | |Error contacting server https://backupaccounting2.teamspeak.com: RESOLVE_ERROR: Host not found (authoritative)

I have released port 2008 and 2010 TCP. Why am I getting this error message? The accounting port is 2008, isn’t it? TCP should be correct. Otherwise everything is working as it should.

Please help me. Thank you very much

Old accounting is on port 2008. The new system is a proper REST api on port 443.
See https://support.teamspeak.com/hc/en-us/articles/360002712257-Which-ports-does-the-TeamSpeak-3-server-use

OK, I have now released 443 as TCP.
I have reloaded the firewall settings. So far I haven’t received any error messages. But accounting reports every 24 hours anyway?

If I run the ping command on my Windows computer on accounting2.teamspeak.com, it carries out the pings. On the server it has 100% packet loss. If I deactivate the firewall settings, I also get 100% packet loss. Strange.

root@teamspeak:~# ping accounting2.teamspeak.com
PING accounting2.teamspeak.com (104.18.5.167) 56(84) bytes of data.
