First check: Java uses unstablesmp.net. Bedrock uses unstablesmp.net with port 19132.
- Confirm the server address is spelled exactly unstablesmp.net.
- For Java, remove any old saved entry and add a fresh server using unstablesmp.net.
- For Bedrock, confirm the server address is unstablesmp.net and the port is 19132.
- Restart Minecraft if the server list is stuck on an old address.
- Use the Discord guide 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.
