Hello,
I’m experiencing an issue with my TeamSpeak 3 server license validation. My server (TS3 3.13.8) shuts down every 2 hours with the error:
license expired, shutting down!
After investigating, I found that accounting.teamspeak.com (51.89.9.102) is unreachable on TCP port 443 from multiple different networks and providers:
-
OVH dedicated server
-
OVH VPS (bot server)
-
DigitalOcean VPS (New York)
In all cases, ICMP (ping) works fine with ~98ms RTT, but the TCP connection on port 443 times out and never completes the handshake. The traceroute shows packets entering OVH’s internal network and disappearing around hop 14.
This does not appear to be a local firewall issue on my end — I verified that outbound TCP 443 works correctly to other destinations (e.g., ifconfig.me, google.com), and my local firewall has no outbound restrictions.
License details:
-
Type: Activation License
-
Valid: 2026-07-01 to 2027-07-01
Could you please investigate whether accounting.teamspeak.com is experiencing connectivity issues or blocking certain IP ranges?
Thank you.
