Only works if we do not specific port here:

# dog -q example.com -H --nameserver="https://1.0.0.1/dns-query" --time

Seems this issue is related to https://github.com/ogham/dog/issues/15

Sadly the DoH service I would like to test does not serve on 443 port. I have to specify the port someway.

I see you found issue #15 :) Like I said there, eschewing --port was done on purpose but turned out to be a bad idea. Thanks for the detailed report.

Hi @ogham , I think that "port in doh" is different from the "--port in query" of #15 . For the doh situation, if i want to test my self-hosted doh server that deployed on a non-stand port other than 443

For example both dog -T @8.8.8.8 google.com and dog -T @8.8.8.8:53 google.com and even dog -T @8.8.8.8:666 google.com is fine.

But dog -H @https://8.8.8.8/dns-query google.com will work, while dog -H @https://8.8.8.8:443/dns-query google.com wont
