To resume a deploy, pass the recovered keypair as the
[BUFFER_SIGNER] to `solana program deploy` or `solana write-buffer'.

This is just a timeout error message. It happens from time to time depending on the network availability
Follow these steps and run again. I've also found that you'll want quite a bit more sol in your wallet than you think you need.
To resume a deploy, pass the recovered keypair as the
[BUFFER_SIGNER] to `solana program deploy` or `solana write-buffer'.
