Problem

You may encounter the "Server Not Reachable" error due to various reasons preventing access to the MDM server.

Cause

The error can be caused by one or more of the following issues:

• Server Stopped: The server may have been stopped or turned off.
• IP Address Change: The server has been configured with a new IP address.
• Server Migration: The server has been migrated to a different location or setup.
• Computer Shutdown: The computer on which the server is installed has been shutdown.
• Firewall Ports Blocked: Ports required for server communication are blocked by the server’s firewall.

Resolution

1. Verify Server Route:
   • Open the command prompt.
   • Type tracert followed by the server's IP address. For example: tracert 101.104.12.104.
   • The TRACERT diagnostic utility determines the route taken to a destination by sending ICMP echo packets with varying TTL values.
   • The command can help identify where a packet stopped on the network.
   • Example:
     C:\>tracert 22.110.0.1
     Tracing route to 22.110.0.1 over a maximum of 30 hops
     1 157.54.48.1 reports: Destination net unreachable.
     Trace complete.
2. Ping the Server:
   • Ping the server IP (ip) using a browser to check if it connects
   • Type the server IP and port in the browser's address bar. For example: http://101.104.12.104:8080.
   • Observe any errors thrown by the browser, which can provide clues to the connection issue.
3. Check Firewall Ports:
   • If you still cannot reach the server, verify the port numbers that need to be open on the server's firewall.
   • Ensure that the necessary ports for MDM server communication are not blocked.
