Retweet error Invalid or expired token Suddenly


I have been using REST API v1.1.

The following error message two days ago.

401:Authentication credentials ( were missing or incorrect. Ensure that you have set valid consumer key/secret, access token/secret, and the system clock is in sync.
message - Invalid or expired token.
code - 89

Again, it does not improve by authentication in a different API.

It is not possible to retweets, but you can only tweet.

Will the regulation of retweets has been enhanced with Twitter side?
