Unexpected Disconnection on Entering Map

I get an unexpected disconnection event whenever I open and enter a map.

If a party member opens the map, we both get the same issue.
If a party member opens the map from an instance I am not in, I can enter the map fine.

I am not sure what I can do about this. I logged out from the game for ~30 minutes and had the same issue when I got back. I am unable to run maps by myself.

I was able to load a map on my own, however the problem persists in a guild hideout with another person in my party.

Been having a similar issue since the event started.

I am able to open maps in my own hideout so long as I am NOT the party leader. If the leadership gets passed the maps return to being bricked upon opening.
