Cast calls via Etherscan

[amarcu]

I'm trying to fetch the storage layout of a contract via cast storage. Any individual storage is fetched without any issues but for the full layout via an etherscan api key i get this error:

➜ cast storage --etherscan-api-key $ETHERSCAN_API_KEY --rpc-url $MAINNET_RPC_URL 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2
Error: 
Received error response: status=0,message=Something went wrong., result=None
➜  cast etherscan-source 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 --etherscan-api-key $ETHERSCAN_API_KEY  
Error:

Installed versions:

foundryup: installed - forge 0.2.0 (477b345 2023-12-18T00:29:33.818665000Z)
foundryup: installed - cast 0.2.0 (477b345 2023-12-18T00:29:34.055926000Z)
foundryup: installed - anvil 0.2.0 (477b345 2023-12-18T00:29:33.930941000Z)
foundryup: installed - chisel 0.2.0 (477b345 2023-12-18T00:29:34.173996000Z)

I checked my Etherscan api key and it's valid. Not sure if this is a cast / etherscan issue or If I'm missing something else.
