From what I understand, issues occur when the fare class you're booked into won't allow you free-of-charge ASR. I've had trouble last year with S fare tickets not letting me do ASR. Then again, their IT systems seem to have gotten an overhaul, because I also had issues getting a seat with a J fare last year, and that included not being able to get one during OLCI or even at the gate.
Assuming that you've tried ASR and failed on LH.com, you can try the LH website again at T-23. Failing that, your next step would be to call them. Make sure that when you log into LH's site, you use the LH record locator, not the UA one. You can find it by logging into UA.com, viewing your itinerary and clicking on the "show additional confirmation numbers" link at the top.
I didn't want to pay for ASR so I'm talking about how best to select my prefered seats during the T-24 checkin window given that I will have to check in with UA.
