"Safari can't open this page because the server can't be found." for sites without "www" prefix. #2261

Comment

I have been receiving this error for many domains for the last few weeks or so:

“Safari can't open this page because the server can't be found.”

This issue seems to involve domains without the “www” in front. I have noticed it on many redirect links such as https://twitter.com/*, https://reddit.com/*, https://github.com/*, and others, all without the “www.” Links to these sites work fine with Adguard enabled if they contain the “www” prefix. All other sites with “www” work as expected with AdGuard enabled.

I have seen discussion online that there have been significant changes to iOS 17.1.1 Safari, as well as AdGuard Pro iOS 4.5.1 (as a response to bugs from iOS 17 changes), so I am thinking it has something to do with this.

Thank you

The issue appears to be fixed-- it seemed to have been caused by the Adguard Cookie Notices filter v2.0.28.64 under DNS filters, which I added a long time ago with no issues, so not sure if the recent iOS 17 updates or the filter list updates broke it. I've now turned the list off under DNS filters and the mentioned sites all work again as expected :).

Thanks very much!
