A "Timed out waiting for client connection" error usually indicates that a timeout occurred while waiting for a client connection. This can be caused by some of the following common issues:
Network connection issues: Check that the network connection is working and make sure the client can communicate with the server. Make sure that the server's IP address and port number are correct and that the client can access the address and port.
Server load is too high: If the server load is too high, it may not be able to process client connection requests in time. In this case, the timeout waiting for a client connection may need to be adjusted. You can try increasing the timeout or upgrading your server to improve performance.
Firewall or proxy restrictions: Check your firewall or proxy settings to make sure they are not blocking client connections. Sometimes a firewall or proxy may restrict communication between the client and server, causing the connection to time out.
Client is misconfigured: Check the client's configuration files or parameter settings to make sure they are configured correctly. It may be necessary to check the client connection timeout settings and adjust if necessary.
