Genesis 40:8

And they said to him, We have dreamed a dream, and there is no interpreter for it. And Joseph answered, Are not the interpretations of dreams from tile Lord? Tell it now to me.

AND THERE IS NO INTERPRETER OF IT. The meaning thereof is that “there is no one to inform us concerning the future which can be derived from the dream.”
It is possible that they sent for some magicians in the morning, or that there were people with them in the prison, but no one could interpret it. It may be that they said; “There is no one in the world, in our opinion, who can interpret it, for it is very obscure.”

DO NOT (‘HALO’) INTERPRETATIONS BELONG TO G-D? Rabbi Abraham ibn Ezra explained it as saying that “future events destined to come as indicated in dreams belong to G-d, for He alone brings on the dream and lets the future be known, and it is He who makes peace, and creates evil, but in my speaking to you there is neither benefit nor loss.” This he said so that they should not punish him if evil should befall them, or so that they should tell him the dreams and not scorn him.
But if so, there is no sense for the word halo (do not) in this context. is out of place. Perhaps its meaning is the same as that of the word hinei (behold). Thus Joseph is saying, “Behold, to G-d alone belong interpretations, but not to man the interpreter.”
In my opinion the correct interpretation is that Joseph is saying; “Do not interpretations of all dreams which are obscure and confined belong to G-d? He can make known the interpretation of your dreams. Now if it is obscure to you tell it to me; perhaps He will be pleased to reveal His secret to me.”

ופותר אין אותו, as if the Torah had written ואין פותר אותו, “there is no one who knows how to interpret it.” We encounter a similar inverted verse in Ezekiel 33,32 ועושים אינם אותם, which by right should have been ואינם עושים אותם, “but will not obey them. (carry them out)”

הלא לאלוקים פתרונים? The wisdom to interpret a dream is something divinely inspired, seeing that man has been created in G’d’s image. It is therefore possible that even I may have been endowed with such wisdom, even though I am a lowly servant and on top of my misfortune I am in jail. It may therefore be possible that you erred when you said that there is no one who can interpret your dreams.

ופתר אין אותו, they had already asked other people to explain their dreams to them but had not found anyone who could interpret it.

?הלא לאלוקים פתרונים, he was reminded of his own dreams. He was still awaiting the correct interpretation of his own dreams, something known only to G’d. He knew however, that G’d lets you dream certain dreams in order to foreshadow coming events. Seeing that this is so, there must be people who can interpret such dreams, why else would the phenomenon of dreams exist? The reason why their dreams were so confused, i.e. that they perceived themselves to be merely bakers and cup-bearers respectively, was that at the time they themselves were imprisoned and it would not have reflected their psychological makeup to perceive of themselves as occupying positions of authority.

ספרו נא לי, perhaps G’d will grant me the insight to interpret the dream.
