Cant connect to VPS

Hey all I have an application that connects to my vps ip, sql and such.
It is a server application so that people can connect to my game. Ive had it working on a Windows VPS before but it is not seeming to let people connect this time when i run it on the new vps i setup. I can run the same server file on my local machine which connects to the vps ip and such and it works fine and lets people connect, but when i run the exact same program on the vps machine , now no one can connect.
i have opened the ports and allowed edge traversal as well as disabled firewall but it is not working on the ovh windows vps. im very confused, i had this problem before because the proper ports werent open for mysql but i have confirmed that all ports that are in use are opened in the firewall , ive even allowed the server program in the firewall programs but still no luck. Can anyone help me debunk why the vps wont let people connect if the game server program is ran from the vps, but can let people connect if i open it on my local machine. I can confirm they are the exact same file connecting the vps information, and i can confirm ive had it working on a windows vps before.
If i can provide you any more information please let me know . I am using XAMPP.
