I can only connect to my server through local host ip (127.0.0.1), but not through external IP. None of my friends can either. My firewall doesn't block it, my ISP doesn't block it. Here's how it happened (might be important): So a friend told me to make a TS3 server, so I downloaded the 64bit version of the server.(already had the client, and used it, and still can use it). I have Win 7 64 bit. Double-clicked the server icon, and both me and my friend connected to my server (external IP). Then, my internet broke down. I restarted the modem, got a new IP, and made the server again. Now, it's not working anymore. (yes, connecting with the new IP). I tried re-installing both the client and the server, also tried the 32 bit versions, but still not working. Can someone help me?
