ruby - can't install Rails on RVM, OS Linux Mint 17 -

i installed rvm. , followed this guide install ruby 2.1.3 version d , create gemset. after tried install rails 4 executing command:

gem install rails -v 4.0 got error:

error: while executing gem ... (gem::remotefetcher::fetcherror) errno::econnrefused: connection refused - connect(2) "your-dns-needs-immediate-attention.hi.link" port 443 (https://your-dns-needs-immediate-attention.hi.link/quick/marshal.4.8/thread_safe-0.3.4.gemspec.rz)

i researched multiple similair questions non of them solve issue.

first, i'd sec utilize of rbenv on rvm. rbenv super simple , have never had problems cannot rvm. however, looks dns resolution issue. in resolv.conf seek setting dns servers googles. if fixes follow create changes permanent. http://askubuntu.com/questions/157154/how-do-i-include-lines-in-resolv-conf-that-wont-get-lost-on-reboot

edit since didn't work found link https://github.com/rubygems/rubygems/issues/1001, chance comcast customer? if so, link should help, aparently comcast appended wierd domain search path, explain why youre getting issue. hope helps.
