VPN Common error Guide

Below you can find the most common errors using the VPN connection provided by Rego Consulting

1. The VPN process failed to start.  The port is already in use by another process

Description: Another VPN/Application/Process is using the port the VPN connection needs. 
Troubleshooting Steps:

***Note that you should not be connected to a Corporate VPN account while performing these tests***

Test 1: Restart

1. Restart the computer

2. Keeping all other programs closed, launch the AWS VPN Client

3. Attempt to Connect to your Profile

Pass: This means another VPN/Application/Process you started previously used this port.  You will need to identify what that is and make sure only one is running at a time.  Use the method in Test 3 as a way to identify.

Test 2: Different Network

1. Using a separate network than your Office network (such as a home network), launch the AWS VPN Client

2. Configure the Profile if you haven’t already

3. Press connect

Pass: The Network you were on previously prevented you from connecting.  Work with your Helpdesk to resolve the connection issue.

Test 3: Identify Port Usage

If the previous tests fail, this will help identify the issue.  Work with your Helpdesk if you are unable to run the command yourself.

1. Open CMD as an Administrator

2. Type this command: netstat -bano

3. Look for a Local Address ending in :8096 or :35001. 

4. Note the Name of the Protocol (the name is in brackets above the line with the Port Number) and the PID. 

5. Open Task Manger

6. Go to the Details tab

7. Find the PID that matches the PID from step 4.   That is the process using the Port in question.

Work with your helpdesk to see if this is a necessary process and next steps.

Test 4: Alternate VPN Client

Use this test if you need to configure proxy settings in order to connect to the VPN.

1. Navigate to the OpenVPN Connect website (here) and download the client

2. Install the OpenVPN Connect Client.  On Driver Selection, make sure to pick TAP

3. Open OpenVPN Connect and click through the pop ups for first installation

4. Once on the Import Profile screen, click File

5. Browse for the .ovpn file used for the AWS VPN client

6. Name the Profile appropriately, then click Add

Work with your Helpdesk if you need assistance installing the software
