Abyss Dungeon - Locked Out for week

Hello together,

EUC - Thirain

After creating a group for Oreha Preveza [Normal] and starting the instance, it came to several unknown errors after each try to enter the dungeon.

After the third time it did work, unfortunately i started alone inside the dungeon.
The game kicked me out after a few seconds and now im locked out for my weekly entrance.

Everyone else in my group can still enter, but im the only one that is locked out.

Is there anything that you can do about it? It is especially frustrating because of the sparse honing materials that are in the game and this is one of the few sources for it.
