Mystery 403 Message


I am mining tweets from code which is mounted on a server (Amazon EC2 instance) using Twitter 4j. Until yesterday morning this was all working well, however, how I keep getting the following message and have not been able to mine a single tweet for over 24 hours.

403:The request is understood, but it has been refused. An accompanying error message wi ll explain why. This code is used when requests are being denied due to update limits (h ttps:// ng).
message - Missing or invalid url parameter.
code - 195

I am sure that I am keeping well within Twitter rate limits and I don’t actually perform any updates in my code. When I run the same code locally I cannot re-create the exception. I have looked at other discussions and can’t find a solution. Can anyone please help?
