Why DOH at all? I deactivated DOH in the browser and set Cloudflare (1.1.1.1 etc.) directly in the router as DNS server. No problems (Opera 70).

@operaoperandi I know this but why it work with opera 69 and not with Opera 70 ?

Unfortunately I can't say anything about it, because I had always deactivated DOH. But I suppose that this is a bug in the latest version or it " gets stuck " with other settings. I would wait for the next update. Can't take too long.

This is definitely a bug it started happened few versions back and I am using beta versions. Are there any logs we can look to see?

@david-fr Did you test it for at least a couple of days, in different times of the day?

@david-fr It seems that regular DNS server is no longer used as fallback when DOH fails.

Hey, all!
I don't know what's going on since few hours but I have sometimes this DNS error. The sometimes is important because I can't reproduce the error and when I reload the page, it works. So, basically, not a big bug but just an annoying fact.
I googled it, "patched" it: it changed nothing.
Any ideas?

@auxiliumdei Read above, it happens when DOH/DNS fails.

@leocg Thanks for the redirection.
Apparently, this is a bug from Opera 70...
As It was working smoothly before...

@auxiliumdei Nope, it's not a bug. In fact it's due to a improvement, I guess at least.

Before, when DOH server failed, the regular DNS was used as a fallback, what broke the idea of DOH. Now it doesn't happen anymore as it seems.

For me, with the last update 70.0.3728.95 (Aug 5, 2020), all is ok now. DOH work.

@leocg said in DNS_PROBE_FINISHED_NXDOMAIN:

In fact it's due to a improvement, I guess at least.

Starting with the 70th version of the Opera, I also encountered this error. The error is random, disappears after reloading the page. There is no such problem in Chrome. I tried to find out what's the matter through DNSQuerySniffer: sometimes the site's DNS requests pass the DoH function, in this case this error occurs in Opera, Chrome DoH does not pay attention to it.
This appears to be a DoH security feature of Opera, although I'm not sure if it's convenient.

The problem with DOH is starting all over again. Nothing's changed. Still that problem.

I am approaching the same issue. But for me it does work for Cloudflare (build in option), however does not for Quad9 (I pasted their address there https://dns.quad9.net/dns-query ). Anythings new, anyones up?
