      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?

          I've just reported an incident to Opera with the following query:

          I have a problem with DoH (DNS over HTTPS), it seems to work once I select radio button with one of your your defaults, like Cloudflare, it works great. But once I use the customized field, where I have to enter Quad9 address it seems not to take any effect. I use current Quad9 address for DOH:
          
          https://dns.quad9.net/dns-query
          https://dns9.quad9.net/dns-query
          
          and they seem not bo be accepted.
          
          the same happens with other providers as CISCO's doh.opendns.com.
          
          I assume this field is not read correctly by Opera, wherever address we provide it is not taken into account, unless is one of the options available at radiobuttons above. Hope you can find what is the rootcause for this issue. Thank you!

              @indiced I tried different DNS-over-HTTPS servers at Opera. DoH function works.
              https://dns.quad9.net/dns-query
              https://doh.opendns.com/dns-query
              https://dns.adguard.com/dns-query
              There is a peculiarity. If the copy-paste method is used, after pasting the address, press Enter, then Opera will remember it.

                @johnd78 I have tried out your method, and it didn't work.
                I managed to reinstall Opera 70, but the issue still persists.
                I can say also, that I run Win10 machine with RTL8111H.
                It seems browser does not read anything from that field, regardless if I press enter, or not.

                  @indiced Judging by your video, you are fine, quad9's DoH is working.
                  If https://dns.quad9.net/dns-query is selected - DNS servers from ISP WOODYNET-1 are used, it should be so.
                  Try https://doh.opendns.com/dns-query - then in this test you will see DNS servers from IPS OPENDNS.

                    @johnd78 Thank you John, I must have had not recognize the WOODYNET as Quad's 9 property. So, there is no problem eventually. Thank you all for your support! Take care

                      @david-fr said in DNS_PROBE_FINISHED_NXDOMAIN:

                      If I disable DNS-over-HTTPS on Opera, I don't have this problem anymore.

                      "If I disable DNS-over-HTTPS on Opera, I don't have this problem anymore." This worked for me too. But I was having problem only with www.alixpress.com. Not with other web pages. But I'm not shure if it is safe to keep the configuration above. Regards.

                        I think, this is due to Quad9 itself. They have a very limited size or basic routing tables on servers that support DNS over HTTPS.
                        I found it, due to the fact they were able to read some of the most popular sites, but for many which are not as high in the popularity rankings they just don't have them.
                        It seems Quad9 for DOH, is just a small stub, in comparison to their usual 9.9.9.9 servers.

                          Just updated to 71.0.3770.171.
                          I don't think there's a problem anymore.
                          DOH is enabled.

                              Sometimes, the Chrome settings or the experimental features can be changes and cause the error. To fix DNS error on Chrome, you have to reset the chrome flags following the steps:

                              Reset Chrome Flags to fix DNS error on Chrome:

                              Step 1:** First, go to the chrome://flags on your browser.

                              Step 2:** Now, you have to click on the Reset all to default. To restart the chrome flags.

                              Step 3:** Finally, restart your computer and check the error.

                              If this method doesn’t work… I read a article that shows 7 steps to Fix the DNS_PROBE_FINISHED_NXDOMAIN Error
                              . You can this this article
