Reasons and Solutions

There can be many reason behind seeing the httplib.BadStatusLine exception. As per Why am I getting this error in python ? (httplib) some of the pottential reasons and solutions are:

• You may be trying to use http:// instead of https://
• The URL string may be containing a trailing newline character. So make sure that your URL are stripped of any leading or trailing special characters.
• The Web Server may be down and Not Responding.
• The Server may be closing the connection before sending a valid response.
• Presence of Content-Length within the http header can also create this exception.
• If the time interval between two requests are more than he configured time of Keep-Alive timeout=n.
• An easy solution would be to establish a new connection through conn.connect() before sending each request.
