I have created a web app using Flask and have used modules like beautifulsoup4, urllib. Now, whenever I send a request to the URL, to which I want to, using urllib.request.urlopen(myurl) it throws an internal server error. The interesting thing is my web app works perfectly fine on my localhost and also if I try opening any other url using urllib.request.urlopen(otherurl) it opens up just fine. What maybe the possible reasons behind this?
