# Endpoint Central Server Not Reachable!

## Problem

You have problems in reaching the Endpoint Central server or Distribution Server, and you run the "Agent Diagnostic Tool". You get an Error **"Server Not Reachable!"**, during the process.

## Cause

You will encounter this error due to one or more of the following reasons:

1. Endpoint Central Server/Distribution Server has been Stopped
2. Endpoint Central Server/Distribution Server has been configured with a new IP address
3. Endpoint Central Server/Distribution Server has been migrated
4. Computer on which Endpoint Central Server/Distribution Server has been installed has been shutdown
5. Ports blocked on the firewall of the Endpoint Central Server/Distribution Server
6. Newly added agents cannot contact the server if the license limit has already reached.

## Resolution

You need to verify the following steps mentioned below:

1. Open command prompt and type **tracert** followed by server's IP address.  
   For Example: **tracert 101.104.12.104**

2. The TRACERT diagnostic utility determines the route taken to a destination by sending Internet Control Message Protocol (ICMP) echo packets with varying IP Time-To-Live (TTL) values to the destination.  

   The TRACERT command can be used to determine where a packet stopped on the network. In the following example, the default gateway has determined that there is not a valid path for the host on `22.110.0.1`.  
   There is probably a router configuration problem or the `22.110.0.0` network does not exist (a bad IP address).

   **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.
   ```

3. Ping the server IP (ip:port) using a browser and see if it gets connected. You can open the Central server console from the agent machine to check the connectivity.

4. **Telnet** the central server from the agent installed device. To telnet, open the command prompt and run the command:

   ```
   telnet <Server Address> <Server Port>
   ```

   Run this in administrator mode.

5. If you still cannot reach the Endpoint Central server, then verify the port numbers that need to be open on the Endpoint Central firewall.

**Note:** If a proxy connection is enabled between agents and server, disable the connection to check the connectivity.

In case you are not able to troubleshoot the error and the problem still persists, then contact support team with the [Log files](https://www.manageengine.com/products/desktop-central/logs-how-to.html#logs).
