I'm glad you find the Proxy Server mod helpful! It's a handy tool to have in your arsenal, especially when trying to connect to servers that may be blocked or restricted. Finding proxies that work with your specific game or server can sometimes be a trial-and-error process. However, a good resource to start with is the website https://soax.com/iran-proxy. They have a list of socks4 proxies that you can try out. Remember that not all proxies will work with every game or server, so you may need to try a few before you find one that works. But once you do, it should make connecting to the server a breeze!
