The server starts but I cannot connect - TS3 VPS

Hello, I bought an OVH VPS to host my Team Speak server. I chose CentOS for its configuration.
At the time of installing the server everything runs fine, and even generates the server kernel admin, but when connecting through TS3, an error appears when connecting to the server. Everything went correct in the installation but I cannot connect, any solution?

Sorry for my English.

If you still haven’t solved this issue feel free to pm me I’ll help you up ^^
