Our web app shows an error message "Name servers did not respond [45.84.187.166, 45.84.187.168]."

If I open a Google Cloud Shell and try from there:

$ dig @45.84.187.166 burgasnet.com

; <<>> DiG 9.11.5-P4-5.1+deb10u5-Debian <<>> @45.84.187.166 burgasnet.com

;; global options: +cmd

;; connection timed out; no servers could be reached

It appears your authoritative servers (or some network in the path) are blocking packets to or from Google.  We are observing this behavior from all locations in the world.  You might want to check our list of egress IPs in each region ( https://developers.devsite.corp.google.com/speed/public-dns/faq#locations_of_ip_address_ranges_google_public_dns_uses_to_send_queries ) and cross reference it against firewall rules or similar settings.
