I am unable to pass through the preview tool. My tags are okay. They work absolutely fine with the tool. However, the URL I am using is quite long (more than 180) and does not end with HTML or similar extensions. I keep getting the following error:
“Looks like something is technically wrong. Please try again in a few minutes.”
I saved the whole page I have to a .html file and put that somewhere on the same server. Now, the same HTML code is returned, only URL is different. Strangely enough, it worked!!
I searched the docs to find if there is any restriction to URL, I found nothing. Please, help!! what could be the issue? Is this a limitation twitter cords have?
