Today, my Pidgin IM client started giving the error, “Received unexpected response from http://api.oscar.aol.com/aim/startOSCARSession”, when connecting to the AOL Instant Messenger (AIM) server. Apparently, it can also happen when connecting to ICQ. Fortuantely, the fix/workaround on Windows and Linux is really easy.
- Go to Accounts
- Modify the AIM or ICQ account
- On the Advanced tab, clear the checkbox labeled Use clientLogin
Are you using Adium? It may also have this issue on the Mac. If you’ve solved it, post the steps in a reply.
Update: Alternatively, in step 3, you can clear the checkbox labeled Use SSL
