Curl Error 28 on a VPS machine

Hi, I opened a 5m server on a vps machine, the server is just fine, you can see it in server list and the server gets a heartbeat. The only problem is that I cannot seem to join it. I get a CURL ERROR CODE 28(timeout limit was reached) error everytime which I believed was a firewall issue, but it isnt. I have disabled my firewall on my vps and still cannot seem to connect from any device to the server. Any knows a possible fix?

Thanks,
Poyraz
