I tried removing the service using the form on the FAQ page and readding… still offline. says its ‘not authorised’ now.

Strange, there is lots of users online.
Do you use another client at the same time ?

I only use the XMPP plugin from pidgin.

I mean another Twitter client ?
If you have make too many requests with your account, Twitter API send an unauthorized error.

nope. only thing I use is your service. aside from intermittently checking online…

What is your IM domain ? It is possible that the server to server connection between twitter.tweet.im and your domain is not working.

Im using jabber.org

I checked and everything should work for you, but we do not see any incoming presence from you. It is possible that you client does not suppor transport addition to the contact list.

it was working before…

I had three contacts… I removed them all, how long should I wait before trying to sign back into it?

also, have you whitelisted your IP? http://twitter.com/help/request_whitelisting
