Getting response 200 but still file not uploaded

[sp1rs]

Three steps
conn = tinys3.Connection("xxxx", "yyyy", default_bucket="zzzz", endpoint="pqr")
f = open('x.txt','w')
conn.upload("x.txt", f)

Same problem here.
I uploaded more than a thousand images, and then it starts to throw HTTPError: 403 Client Error: Forbidden for url: http://s3.amazonaws.com/...
So, articles said to add an endpoint, and with s3con = tinys3.Connection(S3_ACCESS_KEY,S3_SECRET_KEY,default_bucket=S3_BUCKET,endpoint='s3-us-west-1.amazonaws.com') it shows 207 '[I 151112 16:20:46 connectionpool:207] Starting new HTTP connection (1): s3-us-west-1.amazonaws.com'
But I can't find the file in the bucket.

Sorry, I found that it shows the connection was made but the credentials that I passed was wrong.
I put the right credentials and the file are now uploading without problems.
