Key facts
| Fact | Detail | Source |
|---|---|---|
| 4001 | EIP-1193 defines this error for a user-rejected request. | [1] |
| 4100 | This error indicates the requested method or account is unauthorized. | [1] |
| 4901 | The provider is disconnected from the requested chain while connected to another. | [1] |
Connectivity does not equal account permission
EIP-1193 uses connected to mean the provider can service RPC requests to a chain. An application can still lack permission to use an account. Conversely, a remembered account selection does not guarantee that the current endpoint can reach the requested chain.
Look for an account-authorization prompt and check the application’s requested network. Do not interpret every connection failure as a damaged wallet.
A wrong-chain request has a narrower fix
Suppose a wallet can serve Ethereum mainnet but the app requests an unavailable chain. Error 4901 identifies that chain-specific problem. Re-entering a recovery phrase would not make the endpoint support that chain.
A rejected prompt is different: error 4001 can mean you pressed Reject. Retrying is appropriate only if you now understand and intend the request.
Determine whether anything reached the chain
A provider error alone is not proof of a failed included transaction. If a transaction was submitted, follow its hash on the correct network and inspect the receipt before sending a replacement payment.
Applications should react to account and chain changes rather than retain a stale selection. For users, refreshing or reconnecting through the documented interface can resolve stale state without deleting recovery material.
Direct answers
Questions people ask
Does every connection error cost gas?
No. A rejected or unavailable provider request can occur before any transaction is submitted. A gas charge concerns executed onchain work.
Should support need my recovery phrase to fix a connection?
No. Public account, network and error details are sufficient for ordinary connection diagnosis. Sharing recovery secrets creates a separate account-control risk.
Inspect the evidence
The answer and key facts have stable claim links. These records retain the scope and qualification when reused.
A dapp connection failure may mean the user rejected a request, the app lacks account permission, the requested method is unsupported or the provider cannot serve the chain. These are distinct from an onchain transaction reverting. Check the selected wallet, requested account and network, then inspect the precise error before changing settings or resubmitting transactions.
