Is the Unknown host () the name of your website ?
Is this error on the back-office log, or in the front-office log ?

this exception show up in both place: back-office and front-office.
I get this exception from cms-2014-12-05.log file.

According to error log message, maybe it is redirect error, can you help with that?

When access to below URL:
index.html --->java.net.UnknownHostException : (exception trace as my reference before).
When i access to below URL: --->it is ok.
home.html alias as index.html.

No idea, very strange error. Maybe its an Apache HTTP conf error?
Consider using index.html as main url and home.html as an alias.
Is your alias an Ametys alias? or an Apache HTTP alias?
Moreover if this error is not always happening, could be an conf issue in your DNS, or system ; but I don't think this could come from Ametys.

No, it totally can be. It really depends on you VPN... and I will not be able to help you through
