Safari slow on Catalina Beta

Since installing macOS Catalina Beta, Safari takes 5 minutes or more to load google.com.

I've cleared History but the issue remains.

I also have a related problem in that my FTP software fails to connect now with Catalina Beta (Transmit & FileZilla).

How do I troubleshoot this please?

Solution 1:

Checking the network settings I saw a hide.me VPN active.

Disabling this resolved the issue.

No idea how it got installed.
