@kane12 thank you so much for the reply.

I have tried:
Resetting Opera Browser.
Changing to (optimal) and other locations.
Disabling Firewalls.
Reinstalling Network Adapter (Device Manager)
Troubleshooting for the last 2 days.
uninstalling and reinstalling VPN PRO software.
updated Opera Browser to latest.

Still the same.

Note: Free VPN works fine.

I am not able to use VPN PRO, even in trial period.

Fee VPN is working fine.

VPN PRO keeps cycling between

Unprotected, Connecting, Protected,

Unprotected, Connecting, Protected,

Unprotected, Connecting, Protected,

infinitely.
