queryNs ESERVFAIL example.com - on all domains?

[jayonrails]

Hi,

I cannot change the DNS Server settings in my domain settings for a domain, because Cloudron says:

queryNs ESERVFAIL example.com

When trying on the terminal as stated here:

@girish said in Domain setup shows 'queryNs ESERVFAIL':

@SignalScout On the server, please try host -t NS example.com 127.0.0.1 . Does that work? Sometimes, it takes a bit for the NS of a new domain to propagate. One just has to wait it out.

root@my ~ # host -t NS example.com
example.com name server root-dns.netcup.net.
example.com name server third-dns.netcup.net.
example.com name server second-dns.netcup.net.
root@my ~ # host -t NS example.com 127.0.0.1
;; communications error to 127.0.0.1#53: connection refused
;; communications error to 127.0.0.1#53: connection refused
;; no servers could be reached

I don't know how to fix that, I cannot get my domains running. The result is the same for all domains, so I think it is a general error on my server.

How to get deeper on this?

@jayonrails host -t NS example.com 127.0.0.1 is obsolete from Cloudron 8.2 . This is not expected to work.

• host -t NS example.com - this should also work. this is system dns
• host -t NS example.com 127.0.0.150 - this should work. this is unbound

[jayonrails]

Thanks for clarification. This works, but doesn't solve the problem that I cannot add new domains to Cloudron with the error

queryNs ESERVFAIL example.com

Any idea on that?

[joseph]

@jayonrails So both commands work but still you get ESERVFAIL . Hmmm... Does this happen for all your domains or just a single one? Cloudron is internally querying host -t NS example.com 127.0.0.150 , not sure how the output can be different

[jayonrails]

Thanks for the information, I will wait for one day for all the DNS changes to take place and then try again.

@jayonrails sounds good. Otherwise, if both commands work and things are still failing, please send a mail to support@cloudron.io to debug this further. Can't see how it fails.
