What it means
A transaction that reverts with the raw data 0x5bf6f916 hit the custom error TransactionDeadlinePassed, defined in Uniswap Universal Router. The explorer shows the hex because it does not have the contract's ABI to translate it.
The trade's deadline passed before it was mined, usually because the fee was too low for current congestion.
How to fix it
Retry with a fresh quote and a market-rate fee. The deadline exists to stop stale-price fills, so this revert protected you.
