@HS-Devil Turbo is no longer part of Opera.
If you can access the site using the VPN, then it means that the site (or your ISP or government, etc) is blocking your access.
If other browsers can access the site, try using an extension to change the Opera's user agent to see if it helps.
@leocg I've always had it enabled in settings, but it was only showing up once I manually turned it on, by going to settings. But now it seems to have corrected itself, as it is remaining in the toolbar...
Opera VPN on my PC is working perfect. I have been located in Sweden and Holland so far, without leaving my lounge.
It may only be an upmarket proxy, but for free and unrestricted web surfing use, it is marvellous.
Critics are just making nit-picking noises, it is superb for my purposes.
I had a security alert from my email provider, because the logon was in Sweden instead of my normal UK location.
Proves it works !
@hugheffo You could be dealing with: a defective Opera installation, a defective user profile, some kind of problem authenticating your particular system's https connection handshaking and transactions with Opera's VPN server, or some kind of connection interference by an over-zealous, onboard antivirus program (including some update made to it). If it were a universal problem caused by Opera's VPN mechanism, these forums by now would be flooded with complaints. There are the occasional 'issue' reports here, but nothing like what would result from a complete, universal VPN failure (plus there's @rtomasz 's earlier report that it's working for him in the UK).
Or... it could involve your local ISP blocking either Opera's VPN IP or an entire block of IPs of which Opera is a part. Sometimes that's done either in error or if there's been formal complaints of copyright violations being routed via those IPs.
There are some things to try in isolating possible "local system" causes. First, with all your antivirus/antimalware programs turned off, try to connect via Opera VPN to a known-safe, low/no-ad website (a speed-test site like https://speedof.me/ or similar should suffice) to see if that affects things. Second, with Opera off, you could backup your profile and try resetting (renaming) it to see if Opera can access its VPN when turned back on. Third, you could try a parallel, portable install of Opera to see if that allows VPN access. Last, if you know somebody in your locale using both Opera and the same ISP, ask them to try the VPN and see what their results are.
Have you tried clearing the browser cache, doing so make the browser faster and can also fix the VPN issue. Press Ctrl + Shift + Del hotkey to open the clear browsing data window tick all the boxes especially the Cached images box and files option. Try to choose the option “the beginning of time” from the drop-down menu in the options.
