Few thoughts:
1. As already mentioned, PS uses the position information from your mount. If you are far from the target it will take a very long time to solve and the PS software may even time out.

2. It does not get mentioned often but EQMOD will refuse to sync if the current and the new position are out by more than, I think, 4 degrees (don't quote me on that number, I may not remember correctly). I also can't remember if the limit applies to RA, DEC or both.

3. What is the quality of your images? Enough stars for plate solving?

4. Did you set the correct focal length and the sensor info in APT?

When I have PS issues it is usually because of:
- a very bad polar alignment (setup in a new location)
- I was moving the scope by releasing clutches (to balance it for example) and then forgot to use setting circles to get it back to where I started.
When I have PS issues I use astrometry.net to get the real coordinates of the image and then sync them manually on the mount. After that local PS works fine.

Keep in mind my point 2 above. For example, if your target is 6 degrees out you may have to manually sync twice, first step being 3 degrees out and then second time at the target.
(again, the limit may not be 4 degrees???)
