Problem in getting access to Google ChromeBook user related to DNS and memory

[Gianluca Cavallo]

Hi,

I noted that considering this settings:

- using google chrome on chromebook (last update done)

- DNS set as default  (no DNS over HTTPS encryption)

The system doesn't recognize my user and ask me to set one.

So I can't get the automatic login.

If I set DNS over Https as dns solver I can get access to my chromebook google user automatically with no problem.

So, why this happen ?

What is wrong with the default dns ?

It could be a dns hijackgin attack ?

Thanks.
