I have tried to install K9 Web Protection on my windows 10 x64 machine several times. But every time after pressing install in the following picture, It says Not Responding
And finally I get the following error
I have checked everything and I'm sure that internet connection is active.
I can even enter http://www1.k9webprotection.com/ without any problem.
would you please help me to find the cause of this problem and fix it?
My ping results based on instructions here
