Sekhemas(4rth Ascendency) Dc/Unable to connect

Hello, i've tried to go into Sekhemas to get my 4rth ascendency and at the begining of Last floor(Test of Time) got disconnected with the message : "The terrain generator for the client is out of sync with the server. Please create a new instance and try again."

Soooo i did reconnect(few times) to the game but it keeps showing me same msg all the time when i try to come back into the trial(i was doing it with a friend and he had same issue with this run)

A friend of mine uploaded it just so i can send it in here:
