verify_credentials: "Could not authenticate you"

oauth
api

#1

Hi.
I have a troubles with Twitter Oauth. I hope, anybody can help me. I cannot get data of user by token using the ‘verify_credentials’ method. I used code example for curl from the page
https://dev.twitter.com/oauth/tools/signature-generator/<…>

curl --get 
'https://api.twitter.com/1.1/account/verify_credentials.json' --header 
'Authorization: OAuth oauth_consumer_key="yIBPrG88hsdd9pGgoLX", 
oauth_nonce="5e86b8ad638fa18aa5e1d5274798360d", 
oauth_signature="FF5FeMHGU4s8Z11o9Ur3qaogHIs%3D", 
oauth_signature_method="HMAC-SHA1", oauth_timestamp="1436545669", 
oauth_token="14176154-CLm5L7oNNVRhKgnn49qFKcJ4cbt9PgqW0JZAogXHS", 
oauth_version="1.0"' --verbose

I can get data for my user successful, But for another user i get an error:

{"code":32,"message":"Could not authenticate you."}

Why? Thanks in advance.
