I'm assuming that you are searching for the 86200~86400 values? If so, they only work immediately after finishing a TLSQ.
The "86400" refers to the number of seconds in 24 hours, and it counts down every second until the next TLSQ is available. You could try and guess how many seconds you actually have left based on when you last finished a TLSQ, but it would be far easier to just wait until your next TLSQ becomes available in a day and you can try the 86200~86400 search immediately after.
Also, I think you mentioned that you are in year 2 earlier? There aren't as many TLSQs available in that year, and most start to open up in year 3+. The
