Hi Community,
I researched for a few days now to find the solution myself but actually didn’t succeed:
When trying to authenticate openHAB against Twitter, the following error is printed to the log, a few seconds after the URL was printed to the log.

The machine is running openhab 1.7.1installed with apt-get

[ERROR] [o.o.a.t.i.TwitterActionService] - Failed to authenticate openHAB against Twitter
twitter4j.TwitterException: 401:Authentication credentials (https://dev.twitter.com/pages/auth) were missing or incorrect. Ensure that you have set valid consumer key/secret, access token/secret, and the system clock is in sync.

Any Advices on how to get Twitter authenticated or hints what I might have done wrong?
Thanks a lot!

okay, was a stupid mistake. Didn’t delete the old twitter.pin File of an earlier attempt.

Initial Problem was: /etc/twitter.token could not be written cause of
java.io.FileNotFoundException: etc/twitter.token (Permission denied)

So I changed User in /etc/default/openhab to root:root for the Twitter authentication process and afterwards back to my openhab user.

Is this the common procedure. And if it’s so - wouldn’t it be a great idea to note this in the Wiki? :smiley:
