`Invalid blockhash` error while deploying smart contract

Question

I am trying to deploy the demo smart contract on solana for chainlink price feed but getting an error. I followed all the steps from https://docs.chain.link/docs/solana/using-data-feeds-solana/

$ anchor deploy --provider.wallet ./id.json --provider.cluster devnet

Deploying workspace: https://api.devnet.solana.com

Recover the intermediate account's ephemeral keypair file with
`solana-keygen recover` and the following 12-word seed phrase:

=============================================================================
To resume a deploy, pass the recovered keypair as the
[BUFFER_SIGNER] to `solana program deploy` or `solana write-buffer'.
Or to recover the account's lamports, pass it as the
[BUFFER_ACCOUNT_ADDRESS] argument to `solana program close`.

There was a problem deploying: Output { status: ExitStatus(unix_wait_status(256)), stdout: "", stderr: "" }.

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'.
Or to recover the account's lamports, pass it as the
[BUFFER_ACCOUNT_ADDRESS] argument to `solana program close`.
