    Except if I test the PTR record it reports correctly, only the cloudron server itself is misreporting the result.
    https://mxtoolbox.com/SuperTool.aspx using PTR tool says the DNS name is my.domain.

    @AartJansen that's good to know. Can you check what host -t PTR <public ip> 8.8.8.8 reports on the server? This is querying the google DNS.

        @AartJansen you can check in https://dnschecker.org/ if the PTR record has propagated properly . Otherwise, if you can send me IP address to support@cloudron.io, I can check what we see here. Most likely you have to ask your VPS provider why the name is reverse resolving properly.

          its self hosted, and my ISP set it a long time ago. when I use that site to view my PTR for the IP, all come up as green (and the correct domain) except sitehost in auckland NZ (which is oddly the closest geographically to me). its a red cross.

            @AartJansen I can confirm that the PTR looks correct from here. Not sure why your unbound is not resolving it properly. Have you added any additional configs in unbound? If not, can you write to us at support@cloudron.io and we can debug as to why it's not correct.

                This was resolved in support. There was a static DNS record on the local router.

                  It's kind of odd, that rules been there for many months, I don't remember the exact issue I had that caused me to add it. Which could either be the problem was fixed by it, and will return (I guess that will remind me what it fixed), or it fixed nothing, and I forgot to undo it.
                  Still pretty strange that it started DNS problems so much later.

                      I would test the DNS resolution from other computers in the network. This is happening outside of Cloudron.

                        it just went away, i think the router had a DNS cache thats flushed now. It's no longer being set as the DNS server via DHCP, so I think its resolved.
