First check: Java uses unstable.net. Bedrock uses unstable.net with port 19132.
- Confirm the server address is spelled exactly unstable.net.
- For Java, remove any old saved entry and add a fresh server using unstable.net.
- For Bedrock, confirm the server address is unstable.net and the port is 19132.
- Restart Minecraft if the server list is stuck on an old address.
- Use Discord for announcements and support if the same issue continues.
Most connection problems come from an old server entry, typo, wrong edition guide, or missing Bedrock port.
