Random disconnects when i do Trial of Chaos

I'm giving up on getting the last 2 ascendancy points and farming trials on my character.

My internet is OK, nothing else disconnects like that and, although it happens in other content too, Trial of Chaos is when it most happens.

And I just throw away all my Ultimatums, because the instance closes.

At lease it should be like the Sekhema's Trial, when i get disconnected i just have to redo the trial I'm currently on. (but it's too long, too boring and too not-rewarding-enough)

I play on SA server and my latency is usually around 34~36
