<![CDATA[ERR_TUNNEL_CONNECTION_FAILED when trying to use the VPN]]>Hi,

I use the free VPN version and since around 2 weeks I've got the following error : ERR_TUNNEL_CONNECTION_FAILED
This error occurs on every website and from every VPN location (Europe, Asia and America). The only way for me to get Opera browser working is to disable the integrated VPN.
I reported this bug a week ago but I had no answer.

Is there a way to solve this ?

But are you sure it's safe to ignore Opera this way ? Does navigation via Opera remains protected by KAV (in case I come across a corrupted website) ?

For a solution, you need to whitelist opera.exe in the AV from scanning the encrypted network traffic: Settings -> Security settings -> Network Settings -> Configure trusted applications -> Add -> Select your opera.exe -> Check "Do not scan encrypted traffic" -> Click OK.

I also have an another VPN (AirVPN) and I don't have any problem with it (and of course I never use them both at the same time ^^)
But more important : I have the KB5037768 update that is supposed to fix this Windows problem.
