The issue you are facing:
I am running the NextCloud VM .ova on VirtualBox preconfigured from Hansson IT.
When trying to activate and install the TLS Certificate through Let’s Encrypt (running through the menu.sh script) I get the following error:
DNS lookup failed with nslookup. Please check your DNS settings! Maybe the │
│ domain isn't propagated? │
│ You can use this site to check if the IP seems correct: │
│ https://www.whatsmydns.net/#A/my-domain.com
When I do a manual nslookup I get the following:
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
*** Can't find my-domain.com: No answer
I have verified the domain is populated and has the correct IP address here: www.whatsmydns.net
I am running PiHole + Unbound for DNS
I am able perform a successful nslookup on other computers: Linux, Windows, Linux client on VM.
I have reinstalled the vm appliance from scratch several times.
I have done an nslookup search on these forums and was not able to find anything that was related to this issue.
Any ideas? Thanks for your time and help.
