I might suspect that this isn't the reason. You might copy-paste the wrong address. Chainlink address is an ERC20 wallet and you store it on MEW address or in hardware wallet which is Ledger Nano S. If the address were lack or miss-spelled at least 1 letter or number it shows error and it might not proceed any transaction.

If you're concerned is to recover your lost chainlink, my answer is no. Once it is completed, then, it is a reversible transaction. If you have no access to the wallet where you've sent your link token, the chances of retrieving it are having positive.
