Very happy to confirm VPN is working great again. Thanks, guys!

To stop auto-update, rename opera_autoupdate.exe in C:\Program Files\Opera developer\39.0.2226.0 (or wherever Opera Developer is installed) to something else, such as opera_autoupdate.exe.bak

I've just reinstalled the previous release of Opera Developer from https://get.geo.opera.com/ftp/pub/opera-developer/39.0.2226.0/win/ (64bit version), and can confirm that the VPN works perfectly in Private Browsing on my system (Windows 10). Latest release doesn't. Nothing has changed on my system, so it's clearly something related to this release. Think I'll stick with 39.0.2226.0 for now

@leocg Are previous releases of Opera Developer available? We could rollback to the previous version to check if that's still working correctly. That would rule out any possible ISP blocking. I doubt that's the problem, but perhaps worth confirming.

39.0.2234.0 on Windows 10 build 14342, from the UK. No proxy or third-party firewall or anti-virus software. VPN not working here.

Not working how?

Open new private window, VPN shows blue and enabled.

Try to go to any site, shows "Sending request to <url>..."

Eventually times out. Same for all four VPN Virtual locations.

Worked perfectly prior to this build.
