Card Validation Error


#1

I am trying to validate a card that would link to my website, canvasmagazine.tk/index.htm But I keep receiving this error:

ERROR: FetchError:exceeded 4.seconds to Portal.Pink-constructor-safecore while waiting for a response for the request, including retries (if applicable) (Card error)

I then changed my code up so that it follows the exact same model shown in the developer page. Here is the code:

<meta name="twitter:card" value="summary" />
<meta name="twitter:site" value="@Environmentnyou" />
<meta name="twitter:title" content="In State of the Union Speech, Obama Defiantly Sets an Ambitious Agenda" />
<meta name="twitter:description" content="President Obama defended an activist federal government and challenged Republicans to support him on education, child care and middle-class tax breaks." />
<meta name="twitter:url" content="https://farm6.staticflickr.com/5510/14338202952_93595258ff_z.jpg"" />
<meta name="twitter:url" content="http://www.canvasmagazine.tk/index.htm" /> 

I followed the troubleshooting guidelines to see if there was any error. I edited the .htaccess file to allow all of Twitter’s IP. I have contacted my server and am awaiting response to see if they have any restrictions I cannot see. Since the error was 4 second error, I created a test.htm page that has the same meta tags but only one line of text to cut back the load time to 0.25 according to a few tests I ran. However this had no effect and I received the same error.

Any help would be appreciated to help solve this error.
