Troubleshooting VPN problems: 8 Tips

Here are eight helpful tips on troubleshooting VPN problems. Whether you are working in an organisational setting or as an individual, you will find these tips useful in helping you to troubleshoot different types of VPN problems successfully.

1. Assess the extent of the problem

When faced with a VPN problem, the first thing that you should do is to assess the scope of the problem. If you are working within the context of an office, determine the individuals who are experiencing problems. This will help you to find out whether the problem is systemic or local. Systemic problems affect nearly everyone using the service at your place. Local problems usually affect an individual or a few ones.

2. Check connectivity

Checking for connectivity should be the second thing that you do when troubleshooting VPN problems. Check whether or not you can connect to the remote server. In many cases, VPN problems arise from connectivity failures. If you cannot log into the client server, you will have to focus on specific connectivity issues to determine the nature of the problem. If you can connect to the remote server but you cannot access the network, then you have to move to the next step.

3. Verify connectivity problems

You can pinpoint your specific connectivity problem by changing the device that you use to connect to the VPN service. The idea behind this approach is to help you to determine whether the connectivity problem is peculiar to a given device or it affects the entire system. If you can connect to the remote server using a different device, then you should focus on addressing the device that failed to connect.

4. Check the status of the client

Some VPN problems may arise from the client. It is possible for specific client-related problems to jam the entire VPN service. Such problems usually arise from very technical issues. For example, inappropriate configurations can make it impossible for individuals to connect to the remote server. Also, client problems may make it difficult for users to access the network resources of the VPN service.

5. Check the status of firewalls

Firewalls protect the data in your computer. Many antivirus programs have pre-installed firewalls as a way of helping you to protect your data and increase your level of privacy. However, in some instances, your firewall settings may interfere with your VPN connectivity. So, if your firewall setting is on, you may experience difficulties when you try to connect to a VPN service. Therefore, try to switch off your firewall and see if you can connect to the VPN service.

6. Check the user accounts

When any user account has a problem, it will be impossible for any person to use the VPN service via the account. In many cases, user account problems arise from mismatched login details. Users fail to access the service because the login details that they use do not match those on the server. Therefore, try to log off and back on using the details to see whether or not the details are up to date. If the details are not up to date, you have to update them.

7. Check the configurations of the server

Wrong server settings can interfere with the way some users connect to the VPN. Interestingly, when one or more servers have the problem, only a section of VPN users may fail to access network resources. Once you establish that specific users can connect to the server but fail to access network resources, the best thing to do is to systematically analyse the specific components of the server to determine if there is a problem with the settings.

8. Check the overall performance of the service

VPN services have different levels of performance. Besides, the performance of any service may vary at any given time because of many factors. For example, if a particular server of a VPN service experiences excess traffic, the individuals using the server will experience slow speeds.

Therefore, check the entire system to determine whether the problem that users are experiencing is a result of a widespread VPN service problem.
