Any idea why “Name server: remote.example.com.: host name lookup failure” is presented.

Can you please set DNS to:
1.1.1.1
1.0.0.1

The Protector seems configured correctly, and the domain name can be found using the 2 google dns, so there is no apparent reason for this failure. The only issue I can see from the log file is that the lookup is being done on "remote.example.com.", with a final dot, that shouldn't be there.
