Applying Pythagorean Theorem, your circular FOV is 13.47' . So first of all, you need to see if you've got the index-4205-*.fits. Look at Align/Options/Index files for this. Eventually download it. That said, this field is VERY small so chances are you won't have enough stars in your image to solve your position, except maybe if you're pointing at some object inside the Milky Way.
There nothing to do with this, it's not a bug and you're not responsible. Try with a camera with a larger FOV and it will work fine. I have a Celestron C11 XLT (same focal lengh) and it solves perfectly with my ASI1600.
