Hi @ray2cycle which options did you start bitcoind with?

Fee estimation is disabled when you start up with -blocksonly

It is likely the reason why you are getting this error.

Hi, thanks for your replay, my start cmd just : ./bitcoind -conf=./bitcoind.conf , without -blocksonly

I'm not sure if additional configuration is needed to support estimated fees.

I changed the startup command to: bitcoind -blocksonly=false and the new error was:

{
  "errors": [
    "Insufficient data or no feerate found"
  ],
  "blocks": 0
}

In order to get fee estimation for a target of N blocks, you need to have been running for around 2N blocks to gather data.

Got it, thank you very much

Built v25.0 to try to recreate this

Fee estimation is working as expected on mainnet.

I think this can be closed cc @willcl-ark
