Trying to do ICN-TPE-KIX (or TYO)-ICN but website errors out after selecting each flight segments. There are flights available on aeroplan/united/expert flyer but ANA doesn't price out online regardless of dates.

Is this a routing mpm issue? I recall booking the reverse (TPE-ICN-TYO-TPE) online before pricing around 30k and it wasn't a problem.
