King Ladislaus V visited Buda in February 1456. Ulrich of Celje, who accompanied the King to Buda, confirmed his former alliance with Ladislaus Garai and Nicholaus Újlaki. The three barons turned against Hunyadi and accused him of abusing his authority. A new Ottoman invasion against Serbia promoted a new reconciliation between Hunyadi and his opponents, and Hunyadi resigned the administration of part of the royal revenues and three royal fortresses, including Buda. On the other hand, Hunyadi, Garai and Újlaki made an agreement that they would refrain the King from employing foreigners in the royal administration in June 1455. Hunyadi and Count Ulrich were also reconciled in next month, when Hunyadi's younger son, Matthias and the Count's daughter, Elizabeth were engaged.
