Unable to validate my site, always got internal error



I want to validate my site (it works before).
But I always got 'Internal Error. Try again later’
The same time I try to validate other site with twitter card.
The function is fine. But not work on my site.
Please help me find what’s the problem, thanks.

Example URL: https://blog.othree.net/log/2013/12/21/ipad-air/


More survey on this issue:

I fount if I use bit.ly to shorten the url.
Validator will not have error.
But still fails if I paste the url directly.

And some link on my site also works without bit.ly’s help:

Almost every single article’s link fail and need bit.ly to help.


The Twitter Card may have one or more of the following issues:

The summary_large_image Card type is not whitelisted. Please submit for approval via the validator at https://dev.twitter.com/docs/cards/validation/validator.
A robots.txt file was not accessible to verify access to images/videos. (http://farm8.staticflickr.com/robots.txt)


Thanks, I change summary_large_image back to summary.
I want to apply the new card type so I change the value to summary_large_image.

The issue still happens.
I don’t think its related to robots.txt on flickr.
The strange part is:
If I try https://blog.othree.net/log/2013/12/28/2013/
It fails.
But if I try http://bit.ly/1h3S9M6 (bit.ly shorten url of the above url)
It works.


I am having a similar issue. I have all of the meta tags for summary cards installed but I get timeout errors and internal server errors every time I try to validate. I’ve validated cards for several other sites without issue, so I am not sure why I am having a problem with this one?


I found out why.

I apply 'https://blog.othree.net/log/2013/12/28/2013/'
But the bot access ‘https://blog.othree.net/log/2013/12/28/2013


https://blog.othree.net/log/2013/12/28/2013/ https://blog.othree.net/log/2013/12/28/2013

The last slash is missing…


Can you provide a URL?

I think there are 2 way can help

  1. Not modify the URL from user, I know there is security issues need to care. And I think my case is just a bug.
  2. My server give 404 header back to bot. If the error message include this information. Will much helpful.

Could you please remove the Twitterbot “Disallow” directive entirely from your robots.txt file? You should then be able to validate your Twitter Cards. Thanks!


Thanks! Removed!
I got this about 30 times: "Fetching the page failed due to an internal error."
I got this about 2 times: "exceeded 15.seconds to image-proxy while waiting for a response for the request, including retries (if applicable)"
I got this about 1 times: “small image”


Works! “approval pending” Thanks!
