I cannot access any VPN websites like Surfshark or Nordvpn

[sofasurfer]

I wanted to buy a VPN but for some reason, I cannot access website like Surfshark.com to try or buy:

This site can’t provide a secure connection
surfshark.com sent an invalid response.

Try running Windows Network Diagnostics.
ERR_SSL_PROTOCOL_ERROR

I have tried Firefox, Edge, Chrome as well

I then decided to look at NordVpn and again same thing happened?. Why is this occurring, does TalkTalk now allow VPNs?. Surely this isn't right?.

Good morning,

Could you try powering down your router for a full 30 minutes please as this will reset the current session.

Thanks
