Help darkrai free npc reroll ivs issue

[Cobalt23]

When I was reseting ivs on the npc outside alucard's castle, a messesage then pop up "yes or no", then when i was about to click the yes, my account got disconnected then my pokemons ivs are still the same instead of being changed as shown in the screenshot, so i ask the npc again and she wont let me. I spent hours on this quest and I am hoping someone can help me fix this issue/accident thanks in advance.
