Exit all public chats fixed it for me
[UPDATE 3:40pm PDT] - As we continue to investigate this issue, we advise players to leave any public/general chat channels in the meantime as this may help prevent disconnections.
To leave public/general chat, select the gear icon from the upper left corner of the chat frame and select the sub-option 'leave chat'. If you were not already in a public chat channel that option will not be available to you.
Thank you for your continued patience!

Greetings Adventurers,
We are receiving a number of disconnection reports from players across both Europe and North America. Although we believe we have identified the issue in EU, we do ask that those who are still experiencing the issue in NA provide a trace route and post that in the following thread in the technical support forum.
