gem install bundler (or any gem) fails with Errno::ECONNREFUSED: Connection refused - connect(2) for "your-dns-needs-immediate-attention.dev" port 443

It looks like with latest ruby version 2.2.0, I am unable to install any gems as they all fail with:

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    Errno::ECONNREFUSED: Connection refused - connect(2) for "your-dns-needs-immediate-attention.dev" port 443 (https://your-dns-needs-immediate-attention.dev/quick/Marshal.4.8/bundler-1.7.11.gemspec.rz)

I am able to install all the gems with ruby version 2.1.1 just fine on the same machine/network. I am using rvm version 1.26.8.

I have looked at this ticket rubygems/rubygems#1001 but it doesnt seem to apply since ISP is not comcast.

I also tried debugging this further with:

gem install bundler --debug -V

I noticed that I get following additional error:

Exception `Resolv::DNS::Config::NXDomain' at /home/vagrant/.rvm/rubies/ruby-2.2.0/lib/ruby/2.2.0/resolv.rb:546 - _rubygems._tcp.api.rubygems.org

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)

I noticed that it is checking SRV record for _rubygems._tcp.api.rubygems.org which doesn't exist.

Shouldn't it be instead checking for _rubygems._tcp.rubygems.org which does exist? Notice the missing api.

I verified this with directly running the ruby command:

vagrant@vagrant:~$ ruby -rresolv -e "puts (Resolv::DNS.new.getresource '_rubygems._tcp.api.rubygems.org', Resolv::DNS::Resource::IN::SRV).target"
your-dns-needs-immediate-attention.dev
vagrant@vagrant:~$ ruby -rresolv -e "puts (Resolv::DNS.new.getresource '_rubygems._tcp.rubygems.org', Resolv::DNS::Resource::IN::SRV).target"
api.rubygems.org

Any help is greatly appreciated.

"your-dns-needs-immediate-attention”, perhaps?

@indirect 😄
Perhaps.

However, I used http://mxtoolbox.com/SRVLookup.aspx to see if it indeed the DNS config here and even that tool is unable to find the SRV lookup with api in it _rubygems._tcp.api.rubygems.org.

It works just fine for _rubygems._tcp.rubygems.org

Also, as I mentioned, when I switch to ruby 2.1.1 with RVM, I don't have any problem installing gems.

I narrowed down the problem with vagrant. For whatever reason, the vagrant box was not properly working.

I resolved the problem by turning on the natdnshostresolver for the vm box.
