## 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:

     ```text
     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.
