AgNO3 turns milky white???

Hi, I was dissolving AgNO3 in NN Dimethylformamide in one solution, and in another solution i mixed- Methanol, H2O, Nitric Acid. But when I mix the two solution together, a white precipitation forms, which isn't supposed to form. Any tips to prevent this? I want a clear solution in which Silver are completely dissolved in mixing the two solutions. Thanks in advance
