You've ordered the TXIDs around the wrong way...
The first transaction is this one: 56bdf3da128c81602cafb07ed100a55648ab2b67399ee10509e5645bb073e62e
The second transaction is this one: d8063ef9e0affce8233fb914c14961d909a89790efe65c00c40f6bddd76c9e52
Both are unconfirmed. The reason you got the "transaction input unconfirmed" message is that the 2nd transaction (d8063...) is spending the (unconfirmed) UTXO from the 1st transaction. To be able to use the accelerator, you would need to submit the first transaction (56bdf...) and get that confirmed and then you would be able to submit the 2nd transaction.
The "submissions beyond limit" message simply means that it has already queued 100 transactions for that hour... given the state of the network with the big "pump and dump" that occurred the last 24 hours, the accelerator has been getting slammed... if you don't submit in the first half second of a new hour... you're going to get that error message

Thanks HCP. I made the two transactions separately from blockchain.com and made sure that for the second transaction I had enough bitcoins for the transferred amount as well as the fee. I don't understand why I would be spending the UXTO from the first transaction.
