Describe the bug

Trying to deploy my contract and verify it using forge script on polygon but the verification failing every times (I had deployed on sepolia without any issue)

Here my foundry.toml setup :

[rpc_endpoints]
mainnet = "https://mainnet.infura.io/v3/${INFURA_KEY}"
sepolia = "https://sepolia.infura.io/v3/${INFURA_KEY}"
polygon = "https://polygon-mainnet.infura.io/v3/${INFURA_KEY}"

[etherscan]
mainnet = {key = "${ETHERSCAN_API_KEY}" }
sepolia = {key = "${ETHERSCAN_API_KEY}" }
polygon = {key = "${POLYGONSCAN_API_KEY}", chain = 137, url = "https://api.polygonscan.com/api/" }

# See more config options https://github.com/foundry-rs/foundry/tree/master/config

and here the cmd run and the result:

> cross-env && forge script script/01_ImplementationManager.s.sol --rpc-url ${NETWORK} --broadcast --verify --optimize

Just had this happen to me, however it was because I was using an etherscan API key rather than polygonscan API key. I see it might not be the case for you (having a separate env variable for that), but I would double-check that you really have the correct key from polygonscan in there.
