@blackbird71 Another good reason why I won't use Win10/11 I don't want Microsoft involved in apps and extensions.

??? My comment (made several YEARS ago) and this entire thread have nothing to do with Windows10/11 per se... they involve Opera VPN Pro.

By the way, I have been a loyal Opera user since the first beta version came out almost 40 years ago. Am I a fool?

CoId={D8239589-6399-4DE6-8E02-C8F290607EDF}: The user SYSTEM dialed a connection named OperaVPNService which has failed. The error code returned on failure is 87.

Thank you for the error code, it's really helpful! Error 87 can be fixed by clearing your networking cache and resetting your network adapters. Here's how you can do that:

1. To clear your Networking cache:

• Run Command Prompt as Administrator. You can find it by typing cmd in your Start menu search bar. Right-click on it and choose Run as Administrator
• In Command Prompt, type (or simply copy and paste) the following commands. After each command, press enter to use it.
  • First, use netsh int ip reset
  • Next, use netsh int ipv6 reset
  • Finally, use netsh winsock reset

After executing these three commands, restart your computer. Please don't skip this step.
 
2. After completing step one and restarting your computer, reset your network adapters in Device Manager. In order to do this:

• Open Device Manager
• Find Network Adapters
• Uninstall WAN Miniport drivers (IKEv2, IP, IPv6, and so on) You can do this by right-clicking on each one and choosing Uninstall device
• Click Action > Scan for hardware changes. The adapters you just uninstalled should reappear.

You can now try connecting to VPN Pro! If you need further assistance, please contact VPN Pro Customer Support.

@blackbird71 is correct - you do not need to log in or input any information in your Networks settings, this Windows Security login pop-out, or anywhere else in your system settings. The credentials are verified based on you being logged into an Opera account with a valid VPN Pro subscription on your Opera browser.

If the reason for the problem is indeed the app not being able to establish proper credentials or see a valid subscription, here are some steps that may help:

• log out and back into your Opera account - make sure the subscription is visible in VPN Pro settings (they're located within Opera settings). If you can see it, press the Reconnect button in VPN Pro settings.
• delete the contents of the Profile folder, and log into your Opera account so the files are created again. If you're not sure where it's installed, you can check this by opening opera://about and checking Paths > Profile.
• if the above steps don't help, reinstall the app according to the thorough reinstall instruction from this Help Center article:

Please also note that we have noticed that the most common reason for installation issues often turns out to be antivirus software. It is a good idea to turn it off for the time being while following the reinstall subscription to ensure it doesn't interfere with the process. This may also exclude it as a possible suspect. For a long-term solution, please add VPN Pro to your antivirus exceptions.

All that said, there is no way of knowing cause of the issue until we see the details of the error. It is best to start by pressing the blue Error details text on the error message from your screenshot - this will display the specific error code, so that we can go from there!

After uninstalling VPNPro, just for good measure, you can delete the "C:\Users\yourusername\AppData\Roaming\OperaVPNUI" folder too if you want. You can also delete "C:\Windows\SysWOW64\config\systemprofile\AppData\Roaming\OperaVPNService" if it remains. Same with "C:\Program Files (x86)\Opera Norway AS\VPNPro" if it remains.

This problem doesn't occur when I first start opera and then enable VPN Pro.

I'd like to start VPN Pro automatically once I connect wifi.

It seems like you're somehow trying to invoke Opera's VPN in Windows independently of Opera ("automatically once I connect wifi"). The VPN connection software is an internal part of Opera and has to be enabled from Opera.

I would check some Windows settings.
