420 (Enhance your calm) Error still remains after being offline for 3 days

My app was working fine, till one day I encountered 420 error in my streaming, after looking upon the solution, many had suggested to leave log off for 15 minute window, I tried it with almost an hour but the issue persisted, so I didn’t login to my account for straight 3 days to check if that works, but there seems to be no good. Just wanted to know what is the exact problem am I facing, and what could be the possible solution. Has twitter blocked my API access? if yes, then how do I request them to unblock me.
