Why is my Safari unable to open links from Google under VPN?
Copy the URL that gives you trouble and paste it into the address bar. You said that pasting the URL directly works. Does it for that URL?

From there on you can try to reach that server by using the ping command in terminal. You can see if the DNS is properly resolved to an IP and also if any connections are blocked to that IP.

traceroute &lt;host&gt; might also give you a hint on what is going wrong.
