Connection timeout error on account.google.com

Greetings,

I've been using NextDNS for a while with no issues; however, yesterday I started having issues while connecting to https://accounts.google.com/signin/chrome/sync, which was showing a timeout.

Even if the address was able to resolve to an IP, nothing worked, until I changed the DNS servers to a google ones and then it worked without issues, could you help me check this?
