Or HaChaim on Genesis 41:8/אור החיים על בראשית מ״א:ח׳

1 ואין פותר אותם לפרעה. And no one could give a satisfactory explanation for them to Pharaoh. The reason the Torah speaks of "them" is that they were in fact two dreams. Even though the Torah insists that the dream was one, writing את חלומו, when it came to describing the interpretation the Torah speaks of אותם, meaning there was no interpretation for the two dreams.

2The Torah added the apparently unnecessary words לפרעה. The Torah therefore may use the word פרעה as the name of the kingdom, as opposed to it being his personal name. This maybe the reason that when the chief butler addressed Pharaoh, he said: "Pharaoh was angry, etc." It would be most inappropriate for the chief butler to address his king by using his personal name. It is clear therefore that it refers to the kingdom itself. The king was identified with the state. Our view has been confirmed by Rashi on Psalms 34,1. We can now understand why Pharaoh was unwilling to accept the interpretations offered to him by his advisors. Inasmuch as the dream addressed itself to Pharaoh the head of state and not Pharaoh the individual, any interpretations which did not take this fact into consideration did not satisfy him. He felt sure that the dream contained a message of importance for his people. According to one view expressed in Bereshit Rabbah 89 their interpretation was not acceptable "to him;" this interpretation overlooks the fact that the word לו, "to him, does not appear in the text" [I have not found this statement in Bereshit Rabbah 89, Ed.].
