Using a php web application using phirehose streaming API to collect and display tweets according to chosen keywords. It was working fine since months but now giving HTTP ERROR 401 when trying to connect with Oauth as follows -
Connecting to ssl://stream.twitter.com, port=443
Error 401 Unauthorized
Problem accessing '/1.1/statuses/filter.json’
Nothing has changed in the app and I cannot find what is wrong.Please help. Thanks.
