How to force google chrome to make dns requests through wpad?

Greetings!
I have several kiosk stations for students so that they can get acquainted with local resources in the university building as well as wander through a couple of dozen sites.
Firefox was installed at the stations, but it slowed down a lot on certain sites and I had to switch to google chrome.
Network setup is trivial. Addresses of internal resources are resolved in the local DNS. The network has one proxy server that transparently passes clients to a couple of dozen sites. There is a wpad server on which wpad.dat is configured. It has FindProxyForURL and it returns a proxy for this couple dozen sites.
Firefox worked fine if it couldn't resolve a name through local DNS - it would break into wpad and resolve everything through a proxy. Google Chrome flat out refuses to see external sites. DNS_PROBE_FINISHED_NO_INTERNET is the default and permanent response from chrome.

Well @mikes , thanks for making me happy. After you said to check wpad itself, I went to check his site after site and found that only half of the sites were down. In the end, I figured it out and realized that
It will work fine in Firefox if the user types "beeline.ru" in the address bar.
But chrome is either too dumb or too smart. If I type "beeline.ru" in the address bar, it fails. But at the same time it works great with "www.beeline.ru".
After this insight, I replaced all the conditions with:
And everything bloomed and smelled.
Thank you.

WPAD has nothing to do with DNS. Show your WPAD, let's see the config.
