Dextrose solution

[ODUBrew]

So sometimes I may a hooch drink for my friends which is typically table sugar, water, yeast nutrient, and distiller's yeast for high alcohol content. This time I used dextrose and did everything the same but my yeast for some reason isn't taking off like normal. It was in a sealed vacuum bag like normal and I know it's not out of date. It seems to be fermenting very weakly but I pitched a little over a day ago and the airlock hasn't moved since, any ideas what might have gone wrong?

I figured using dextrose, fermentation would be fast. Oh and the yeast was pitched at room temp along with the dextrose solution being at room temp as well.

Yes, I'm saying I've done this plenty of times before with success and have done nothing differently this time except use a different sugar. What could be the possible problems, I figured maybe bad or old yeast but they are plenty in date and the store restocks the kind I got frequently?

If your wondering about the actual drink, we flavor it afterwards, I know it sounds gross but its cheap and not bad
