I'm having a huge problem with ES. When I start up ES and log in with my first user it works fine. It does find the user from the database and the login handler will return back the ChainAction.OkAndContinue value. However, if I log in another user that does exists in the database as well, it hangs. The client doesn't get a response back from the server. Not sure if the message got lost or whatever. Anyway to determine whether the message did get sent to the client? Sometimes it'll work and both login will succeed but later on, one of the plugins eventually hangs as well.
