War match making

We are “The Last Hope” alliance plat 4(rank 21), tier 3 almost about to make it to plat 3. We encountered a war matchmaking “auto cancellation” after it was enlisted.. We are worried this will effect our ratings, scores and chances of hitting plat 3 really badly.. Please sort this out and help us. We don’t want to loose the hopes after all the hard work we put in. Thank you Kabam.. waiting for a good reply..
