SONAR cannot connect to the internet

SONAR cannot connect to the internet, even after turning off the firewall. Does anyone know how to resolve this?

Are you using a VPN? If yes, turn it off. If no, then reboot your computer and try again. Can't hurt to try.

I've tried that already and it failed. What other options do we have?

我已经试过了，但失败了。我们还有其他选择吗？

@xguitar can anything else?

What does the Windows event viewer say?

What Anti virus or malware software are you using?

IIRC, all the Cakewalk Product Center is doing a "HEAD" request from  https://www.bandlab.com - this will be on port 443.   If it doesn't get a reply in 3 seconds, it will show this message.

First check you can access bandlab.com in a web browser  - if you can't, then check your Firewall settings, both on your router and Windows Firewall.

If the browser works fine, check that Cakewalk Product Center isn't blocked in Windows Firewall.
