For years I was able to run autorouting on boards, solving layer 19 (Unrouted) by rearranging components, adapting Net classes track width, adding or adapting polygons etc..
However, after weeks of trying I cannot get autorouting to run succesfully without unrouted tracks on this specific board (files added below).
Can someone please help resolving this issue, or pointing out what might be at stake? I added a zip file with the library, and the .sch and .brd files below.
