Answer 1

In my case disabling of the QUIC (chrome://flags/#enable-quic) in Chrome didn't help. I saw this ERR_QUIC_PROTOCOL_ERROR in all browsers.

The solution wasn't in my computer but on the local network router. I have Synology RT1900ac router with parental control enabled and it uses web-filter for blocking danger or malware sites (in the default setting the basic level of the web-filter is set). And this router's web-filter blocked googleadservices.com webserver that Google uses for redirecting.

So the solution was just to add googleadservices.com to the list of allowed domains (see Network Center > Parental Control > web-filter tab on Synology router administration.)

If you have different router, you can have similer "web-filter" active and encounter the similar problems.
