A Step-by-Step Guide on Fixing VPN Not Connecting Issues

A “VPN is not connecting” error indicates that a virtual private network (VPN) has failed to establish a secure connection between the user’s device and the VPN server. There are several factors that can cause this issue, including network connectivity problems, invalid login credentials, outdated VPN software, or firewall configurations blocking the VPN connection.

When a VPN does not connect, it may display an error message or simply fail to connect without any notification. The user may also experience reduced bandwidth or intermittent connectivity disruptions, hampering access to resources requiring a secure connection.

To fix this error, users can try several solutions, such as verifying network connectivity, ensuring valid login credentials, updating VPN software, and adjusting firewall configurations. They can also contact the VPN provider’s support team for further help if needed.

In this blog, we have explained the common reasons behind the VPN is Not Connecting Error along with the possible steps to fix this issue in no time.

Common Reasons behind the “VPN is Not Connecting Error”

  1. Invalid VPN Credentials
  2. Outdated or Incompatible VPN Software
  3. Firewall Blocking VPN Ports
  4. Local Network Interface Issue
  5. VPN Server Issue
  6. Corrupted System or Network Files
  7. Bandwidth Throttling
  8. Revoked or Expired Account

1. Invalid VPN credentials

The username, password, hostname, or IP address for the VPN server could be incorrect. This is a very common mistake resulting in a connection error.

2. Outdated or incompatible VPN software

The VPN client application on your device may be outdated, damaged or incompatible with the VPN protocol and security features of the VPN server. Updating the VPN client can fix such issues.

3. Firewall Blocking VPN Ports

Your firewall may be blocking the TCP and UDP network ports required for VPN connectivity. You need to configure the firewall to allow traffic on ports like 1194, 500, 4500, etc.

4. Firewall Blocking VPN Ports

Your firewall may be blocking the TCP and UDP network ports required for VPN connectivity. You need to configure the firewall to allow traffic on ports like 1194, 500, 4500, etc.

5. VPN Server Issue

In some cases, the server itself may be temporarily unavailable or face connectivity issues preventing new connections. The issue could be on the server side. Trying a different VPN server can determine if the problem is at your end or with the VPN host.

6. Corrupted System or Network Files

Rarely, corruption of Windows system files or other network configuration files can also lead to VPN connectivity failures. Running the sfc /scannow tool or system restore to fix any file corruption may help resolve such issues.

7. Bandwidth Throttling

Some networks may throttle bandwidth or block certain ports/protocols required for VPN access. Accessing the network from another location can determine if bandwidth throttling is the cause.

8. Revoked or Expired Account

If access to the VPN account has been revoked, or suspended or the account has expired, it will not be possible to connect to the VPN until the account is re-enabled or renewed.

  2. Ensure the VPN Details are Correct
  3. Check for VPN Compatibility Issues
  4. Update or Reinstall VPN Client Software
  5. Try Connecting to a Different VPN Server
  6. Enable or Disable VPN Encryption and Security Protocols
  7. Restart your Router and Modem
  8. Check for System File or Firewall Issues

1. Check Your Internet Connection

Make sure your internet connection is working properly and there are no issues with your router or internet service provider. A good internet connection is required to connect to a VPN.

2. Ensure the VPN Details are Correct

Double-check that the IP address or hostname of the VPN server, username, password, and other details you have entered are correct. Any incorrect detail can prevent the VPN connection.

3. Check for VPN Compatibility Issues

Some VPN services do not support recent security protocols like IKEv2 or certain encryption ciphers. Make sure the details of the VPN you are trying to connect to are compatible with your device and local network setup.

4. Update or Reinstall VPN Client Software

Outdated or corrupted VPN client software can cause connectivity issues. Ensure you have the latest version of the VPN client installed on all your devices. You may need to uninstall and reinstall in some cases.

5. Try Connecting to a Different VPN Server

If possible, try connecting to a different VPN server to determine if the issue is with your original VPN server selection or configuration. This can help narrow down where the problem lies.

6. Enable or Disable VPN Encryption and Security Protocols

You can try enabling various encryption and security protocols like IKEv1, IKEv2, different ciphers, etc., and check if you are able to connect to the VPN. Disabling certain protocols may also help resolve issues with connectivity.

7. Restart your Router and Modem

Resetting your network equipment like routers, modems, switches, etc. refreshes the network configuration and settings. This can often resolve temporary issues causing the VPN to not connect.

8. Check for System File or Firewall Issues

Corrupted system files or firewalls blocking the VPN connection are some other possible reasons. You may need to restore system files, reset firewall default settings, or disable the firewall temporarily to check if it helps.

9. Uninstall and Reinstall VPN Client Software

As a last resort, you can try uninstalling the VPN client software from your system and then reinstalling it again. A clean install may fix any issues present with the previous software install. Follow proper instructions to uninstall and reinstall without breaking your device configuration.

10. Restore Default Configuration

Restore the default network configuration using System Restore to revert to an earlier working point in time. This is useful if a newly installed network device or software is causing issues.

11. Clean Network Caches

Clear your DNS cache, browser cache, Windows cache, and any other network-related caches. This refreshes network configuration and settings.

12. Try VPN Encryption

Tweak VPN encryption settings like AES128/256 or other available ciphers to resolve issues.
