Summary

When the getAddress request has a network mismatch, for example requested Mainnet but wallet is in Testnet, the resulting error message should not be "Transaction failed". No transaction was taking place.

You may have to switch your active network in wallet settings. "

Reproduce steps

1. Run the sats connect example app https://github.com/secretkeylabs/sats-connect-example
2. Change the getAddress request network to a different network than the wallet
3. Press Connect

Show an appropriate error.
