Unable to join The Battlefront from The Marketplace in Act 3

Every time I try to enter The Battlefront from The Marketplace in Act 3, I get logged out with the error message "An unexpected disconnection occurred.".

I tried multiple times from multiple different realms already, same issue every time. Other zones work fine. Because of this, I cannot progress further.

Tried again, it works now.
