Bathroom exhaust fan leak issue

Noticed icicles forming on roof where exhaust fan outlet is. Went to attic and found black mold in the area where the bathroom fan is. The exhaust pipe exits to roof six feet to left. Ideas on how to proceed?

It's hard to offer advice since your photo doesn't show anything of your exhaust system.

If the photo is taken from the fan location, why does it exhaust 6 feet (laterally) away?

If the fan is exhausting 6 feet away why was only this one bay darkened with mold/mildew?
