Oreha Preveza Hard disconnected

Today at Abyss Oreha Preveza Hard, my game disconnected when killing Albion, when I came back my party had already killed Albion and I couldn’t earn the reward and I couldn’t buy the reward chest. Now I can’t get into Abyss Hard, because he counted my weekly turn. I would like to know if there is a way to compensate in my case. Below is the photo of the problem and the message when I tried to buy the chest. Helps pls!
