Pidgin Received Unexpected Response from AIM and ICQ

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.

1. Go to Accounts
2. Modify the AIM or ICQ account
3. On the Advanced tab, clear the checkbox labeled Use clientLogin
4. Save

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
