VPN: "Authentication credentials required"?

  • Same problem. Windows 7 64.

  • Try the following. It works for me.

    Inside Internet Protocol Properties of your network connection: DO NOT obtain IP and DNS server addresses automatically. Assign valid IP and DNS server addresses.

    If you're using Windows 7, right-click on the network icon in the system tray. Go to Open Network and Sharing Center. Right-click on the connection you're currently using. Go to Properties. Choose IPv4 if you're using it. Start from there.

    And, good luck. 🙂

  • The reason you are getting "Authentication credentials required" is because you have not selected a country profile and the VPN location is set to Optimal... see fix below.

    After downloading the new Opera VPN version do the following:

    1. Go to Opera "Menu" at top left of screen and then click "Settings"
    2. Select "Privacy & Security"
    3. Select the VPN option and select "Enable VPN" tick box
    4. Close "Settings menu"
    5. Open a new tab and you will see a small blue icon called "VPN" in the address Bar
    6. Left click on the blue "VPN" icon
    7. It will open a drop down menu showing a blue slider with the Option "VPN ON"
    8. At the bottom of the drop down menu it will have a setting: "Virtual Location"
    9. Beneath this it will have an option box which is set to "Optimal Location" (this is the default setting)
    10. Click the down arrow option to change your location from the default (this is the cause of the problem)
    11. Set the option to whichever country suits you best, you do not want it set as "Optimal Location"
    12. Open a new tab and type in any address and ... Voilà!
      You do not have to change anything on your local PC or notebook as Opera browser is handling all calls using its own VPN ip address, enjoy surfing anonymously 👽
  • This is being fixed now and you should expect an update soon.

  • The reason you are getting "Authentication credentials required" is because you have not selected a country profile and the VPN location is set to Optimal...

    I had tried that. It didn't work for me.

  • Opera 40.0 is out and its VPN is working fine even without tweaking (at least, in my systems). So, you people can leave developer and switch to stable, if VPN is your primary reason for using the former

  • Fixed. Working well

  • I am still having this issue. When VPN is enabled I am unable to to connect to any website.

    Version: 40.0.2308.62 - Opera is up to date
    Update stream: Stable
    System: Windows 10 64-bit (WoW64)

  • I am still having issue. When VPN is enabled i am unable to connect to any sites and getting : Authentication credentials required.error.

    Version: 40.0.2308.62 System: Mac OS X 10.12.0 64-bit

  • I've got the same problem with Opera dev 41.0.2349.0 on W7Pro. VPN worked fine for a long time, but now I cleared my browsing data...

    opera://settings/clearBrowserData

    ...with "Third party services data" checked. Directly after this the error message "Authentication credentials required." is displayed every time I try to open a website with VPN turned on.

    I am pretty sure clearing "Third party services data" caused the error message "Authentication credentials required.", because I cleared my browsing data several times a day before with "Third party services data" UNchecked without having this problem.

    Hope this helps to fix the bug. For the moment I am not able to use VPN anymore with my Opera dev installation 😞

  • Same problem here with the Authentication credentials ... I just figured out that I'm unable to reach surfeasy web site via Opera!!! I think the problem stars here!!! Does anyone have the same problem?? (https://support.surfeasy.com/hc/en-us)

  • The problem seems to be fixed out of nowhere. VPN in Opera dev works again for me without any update or restart since a few minutes?!

  • Hi Guys, the problem should be solved now. Could you restart Opera and check again. Please report if there are still issues with VPN.

  • i have no problem,but please add UK server,thanks

    At the moment VPN works like a charm but a few hours ago it turned several times from blue to orange and back within a second.

    PS: I'd like to see Austria (not to be confused with Australia) and Switzerland as virtual locations.

  • Hi kmielczarczyk,
    For me the issue remains the same 😞

  • I often get this error since the "Authentication credentials required." problem:

  • In addition to my post above this slightly different error message is shown too since the "Authentication credentials required." problem:

  • Hi there,
    Any news regarding the fix of the VPN issue?
    It's a bit strange that with the VPN turned ON, I just can access a few sites that a normaly use.

    For instance I'm not able to load my home page: https://start.duckduckgo.com
    But I can load this one: http://www.sapo.pt

  • Same Issue here! Still!

    Interestingly:
    40.0.2308.15 beta works like a charm WITH VPN active! the final doesn't.
