I use DISQUS on my polymer site, I got this error about three hundred, and I checked polymer-project.org , it had the same problem.
POST https://localhost:26143/skypectoc/v1/pnr/parse net::ERR_CONNECTION_REFUSED
polymer-project.org website:

my site ::

and there are about three hundred requests!
I am using disqus-commnets , for example:
<core-header-panel mode="waterfall-tall" tallClass="medium-tall" > <div class="core-header ">{{response[0].title}}</div> <div layout horizontal center-justified flex class="contentcontainer"> <div flex?="{{!phoneScreen}}"></div> <div vertical flex four style="background:#ffffff;box-shadow: 0 6px 20px 0 rgba(0, 0, 0, 0.19); color: #555;"> <div flex id="content" class="markdown-body"></div> <div flex><disqus-comments shortname="myName"></disqus-comments></div> </div> <div flex?="{{!phoneScreen}}"></div> </div> </core-header-panel>
What reason caused this? What did this error indicate below?
WebSocket connection to 'wss://realtime.services.disqus.com/ws/2/thread/3704740536?' failed: WebSocket is closed before the connection is established.
and DISQUS doesn't even show up in firefix, safari and IE, who have any ideas?
