Delirious Thicket map failed to connect instance

Hi,

I'm desperately trying to enter my T16 Thicket map 60% delirious and it keeps disconnecting me with the failed to connect instance error.
Never happened before (first 60% delirious this league though).

What's is even more weird is that, nothing like previous opened maps, my call to arms Cry keeps playing the sound during the loading screen.

Hope this will reach someone who knows how to deal with this issue.

Anyway, love the game, good luck have fun all.
