@korgen63 I read a post on Slashdot a little before then that a recent Windows update was blocking all VPNs, my guess is that's what happened.

@sgunhouse I'm afraid there's no connection between this update and the vpn issue.
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.

@korgen63 Do you install 3rd party antivirus like kaspersky AV?

@matthoki Indeed, I use Kaspersky Antivirus since many years.

@korgen63 This issue happened due to recent update of kaspersky AV that has an issue with Opera VPN. 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.

@matthoki Thank you it seems it works. 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) ?

@korgen63 I think this will only turn off the AV's warnings for potentially dangerous sites for the opera.
