Under normal circumstances, "node is unhealthy" often means that the node has fallen behind from the rest of the network, so you either need to wait for it to catch up, or you need to use another RPC node.

However, I can tell you that testnet is currently down, so you'll need to use another network until it's back up, either devnet or a local solana-test-validator.
