Is a 10060 error exclusively indicative of the server being completely offline?

No, a 10060 error is not exclusively indicative of the server being completely offline, though it is a common cause. While an offline server will certainly result in a connection timeout, the error simply means the client didn't receive a response within its waiting period. Other scenarios include: 1. **Server Running, but Service Down:** The server OS is up, but the specific application or service that clients are trying to connect to is not running. 2. **Server Firewall:** The server is online and the service is running, but its firewall is blocking incoming connections. 3. **Network Obstruction:** An intermediary network device (router, switch, ISP firewall) is blocking the traffic. 4. **Server Overload:** The server is online but too busy or resource-starved to process new connection requests in a timely manner, leading to timeouts. 5. **Incorrect Target:** The client is attempting to connect to the wrong IP address or port, which may not have any service listening.
