As of September 19th, 2019, Neverwinter will no longer be supporting connection to our internal chat system via an XMPP client. While this feature was interesting and often convenient, it also unfortunately makes it easier for gold spammers and others to reach our chat system. Allowing access via an XMPP client also creates several technical challenges that make it difficult to keep our in-game chat safe and smooth. At this time, we don’t have any plans to replace this with a different service.
Please feel free to discuss this change in this thread, and let us know any further questions. We will be updating this thread with any additional notices or clarifications as needed.
