list two problems that humayun faced when he ascended the throne ?

Shortly after Humayun had marched on Gujarat, Sher Shah saw an opportunity to wrest control of Agra from the Mughals. He began to gather his army together hoping for a rapid and decisive siege of the Mughal capital. Upon hearing this alarming news, Humayun quickly marched his troops back to Agra allowing Bahadur to easily regain control of the territories Humayun had recently taken. A few months later, however, Bahadur was dead, killed when a botched plan to kidnap the Portuguese viceroy ended in a fire-fight which the Sultan lost.
