Can't enter map portals, disconnected with "an unexpected disconnection occured" error (PoE1)

Same with me. Maps worked fine first now... bugged.

Tried maps today for the first time. The very first map (activated while in a party) disconnects me and party member both each time after clicking any portal.
Had to override bugged map with the party member's other map, worked fine (launched in hideout).
I don't have a hideout, so tried to put in another map, but not in a party, worked fine, no bug. The next map after that activated NOT in a party resulted in the bug again, cannot enter it, always disconnect.

I'm having the same issue, lost 2/3 maps so far including the first rare I tried. I'm a noob just starting maps so that kind of stings, will probably hold off playing until this is fixed.
