I keep getting the following error on mainnet and doing the same transaction again works well.
Error: Action failed with error: unable to confirm transaction. This can happen in situations such as transaction expiration and insufficient fee-payer funds
The network is likely congested. Raise the priority fee to make it more likely your tx will be processed in a timely fashion.
Some wallets like Phantom automatically add a priority fee as-needed: https://docs.phantom.app/developer-powertools/solana-priority-fees
