I am trying to import my bitcoin privatekey to my electrum wallet and use that wallet to create transactions.

I restored the wallet using the command electrum restore <private key>

The restore was good and I was able to get my balance to show up correctly via electrum getbalance, everything looked fine until I try to create a transaction, and it gave me this error

electrum.util.NoDynamicFeeEstimates: Dynamic fee estimates not available

Does anyone know why this happened?

I am using the latest electrum.

Edit: The error only shows up with a restored wallet, I can send transactions with my sweep wallet without any problems
