@slm4work Had yu reset DNS setting in Vivaldi after you changed your OS DNS setting?
Which DNS setting do you use in Ubuntu?

[DoctorG]

@slm4work Tested on Ubuntu 22 LTS with Vivaldi 6.8.3381.48 (Setting for Secure DNS Cloudflare).
X opens fast, a second and it was loaded.
Sam if i disable Secure DNS in Vivaldi and use Ubuntu-wide DNS 1.1.1.1 (is Cloudflare IPv4).

1.1.1.1 is also working here, as well as the actual URL https://one.one.one.one/dns-query

The URL can also be used in the same DNS setting, select Add custom DNS service provider
