Why can't the One Master Server and One Volume Server be initiated due to the refusal of connection on port 19333?

edit

There could be several reasons for the refusal of connection on port 19333, which is the default port for One Master Server and One Volume Server communication. Some potential causes include: - Firewall settings: If a firewall is blocking the port, the connection will be refused. Check the firewall settings on both the Master Server and Volume Server to ensure that port 19333 is allowed. - Network connectivity issues: If there are problems with the network connection between the two servers, the connection may be refused. Check that both servers can communicate with each other and that there are no network issues causing packet loss or other problems. - Configuration issues: It's possible that the servers are not configured correctly, which is causing the connection to fail. Check the settings for both servers (including IP addresses, ports, and other configuration options) to ensure they are correct. - Server capacity: If either the Master Server or Volume Server is overloaded, it may not be able to handle new connections. Check the server's CPU and memory usage to see if they are running at capacity. Overall, troubleshooting the refusal of connection on port 19333 will require investigating these and other potential causes to determine the root issue and resolve it.
