Izaro's Labyrinth and disconnects

Please let us somehow resume our current labyrinth runs.
I have disconnects roughly every half an hour. It's basically impossible to complete the labyrinth challenge in that time without rushing through it with an overpowered char.

I get that we should not be able to leave in the middle. But would it be so hard to keep the instance open for the standard duration when the client disconnects AND immediately transport them back there (instead of town) after a fast reconnect?

The way it is right now, unstable servers or network connection lock me out of this content.

This isn't just some random bonus content, ascendencys are a vital part of a characters progression. It's bad enough that the labyrinth has to be done in one sitting, which already takes a considerable amount of time. But nothing is more frustrating than to be close to the last fight and THEN get a dc and having to start again, effectively having wasted an hour or more (when exploring everything)
