Issue with your Minecraft server
Issue with your Minecraft server
You're encountering an issue where the server fails to log in due to an invalid session, even though it appears to be running correctly locally. The error message suggests a problem with the session handling on the remote machine. Check if the server is configured to accept connections from external networks and ensure the firewall allows traffic on the specified port (25565). Also verify that the client is using the correct IP address and port when trying to connect.
In the configuration file, change online-mode to false. Restarting could also be beneficial.
