Chatgpt! Especially when you go to chatgpt 5+ premium website coding! If your servers are showing 0/0 players after upgrading the PC, that almost always means the server query system is not responding, not that the server is broken. Game listings like the one on Rencorner use something called a Steam/UDP query to ask the server how many players are online. If that query port is blocked, misconfigured, or forwarded to the wrong IP, the website cannot read the player count and it displays 0/0. First, make sure the server itself is actually running by launching it on the new PC and trying to connect locally using 127.0.0.1:PORT (replace PORT with your game port like 27015 or whatever your server uses). If you can join locally, the server is fine and the issue is network-related. Next, check your server configuration files or launch parameters and confirm what ports it is using — most Source/Steam games use something like -port 27015 and may also use a query port (often the same port or 27016). Now the most important part: when you upgraded the PC, the internal IP address likely changed, which breaks router port forwarding. Open Command Prompt and type ipconfig, find the new IPv4 address (something like 192.168.1.xxx), then log into your router and go to Port Forwarding. Make sure the game port and query port are forwarded to the NEW internal IP of this upgraded PC, using UDP protocol (most game queries use UDP, not TCP). If the router is still forwarding to the old PC’s IP, the query will fail and show 0/0. After that, you must also fix Windows Firewall on the new PC because upgrading or reinstalling Windows resets firewall rules. Open Windows Defender Firewall → Advanced Settings → Inbound Rules → New Rule → choose Port → select UDP → enter your game port (example 27015) → Allow connection → check all profiles (Private, Public, Domain) → name it something clear. Repeat for any additional ports your game uses. If you want to be extra safe, create outbound UDP rules as well. Once router forwarding is correct and firewall rules are open for UDP, restart the server completely and test it from outside your network (for example using the game server browser from a different connection). If everything is configured correctly, the server will start responding to queries and the player count will update instead of showing 0/0. In almost every case after a hardware upgrade, the problem is either wrong internal IP in the router or Windows Firewall blocking UDP query traffic, so fixing those two things properly will solve it. If you tell me whether this is hosted at home or on a dedicated/VPS server, I can tailor the exact ports and commands for your specific game so it works 100%. Chatgpt wrote that! So maybe it can help i dont know but i guess it can maybe help

Do you think you can fix it? On a forum plugin that has only ever half-assed worked, on a minecraft server that has no developer to upgrade it anymore. 

so u read, a developer, and dont do anything? what is the point of your rank then!!!

the cheap version of the above tactic, surprisingly effective but needs more players than shown.
