You might want to have a look at these two pictures:
https://prnt.sc/o0ffed - My view on latest players (That's also your timezone: CEST)
https://prnt.sc/o0fgoh - Start of the war, picture taken from our stream, all players
I'll try to explain my thoughts on these pictures now:
These pics combined show the order you all (and our team ofc as well) joined the room. Obviously Miguel was first, followed by Kratos, Aketx, Diego, WaMi and ApG77. That's 6. You joined after them, according to pic No. 1. That seems odd, as you said you weren't sure about Aketx making it in time. He was in the room before you were, and not even as last of your players, but as third. The fact that you don't show up after Diego shows, that you didn't reconnect to the room after his DC. Nothing more, nothing less. It doesn't show what happened between 20:01 and 20:33. And as you can see with my last playtime with for example Devoty, it shows when you started playing with all the other players, as that's when the room for the war vs. AU was opened.
I'm not going to assume things, but it looks kinda wrong if you say you weren't in the room at all, just online.
