# Limitations

When making requests to Solflare in [Establishing a Connection](broken://pages/-MVTpFiMjCZoOS8Mh5WD), [Sending a Transaction](broken://pages/-MVTqCIA_jpCwXFFlZd1), or [Signing a Message](broken://pages/-MdZE5Mw0ygjopm7xLzJ), Solflare may respond with an error. 

### Errors

The following is a list of all possible error codes and their meanings. These error messages are inspired by Ethereum's [EIP-1474](https://eips.ethereum.org/EIPS/eip-1474#error-codes) and [EIP-1193](https://eips.ethereum.org/EIPS/eip-1193#provider-errors).

Typically, these errors will be easily parseable and have both a code and an explanation. For example:

```javascript
try {
  await window.solana.signMessage();
} catch (err) {
  //  {code: 4100, message: 'The requested method and/or account has not been authorized by the user.'}
}
```
