I started the node but after a few hours it stops working. what could be the reason for this? In alchemy I see that I can repeat or the error with eth\_getBlockByNumber. Inside nod see this WARN fuel\_core\_upgradable\_executor::executor: 407: The block version(1) is different from the native executor version(0). The WASM executor will be used. is this the reason why he stop working? ---

HI @Patrycjusz , Thanks for this. Can you first provide the `fuelup show` results? Also, can you try restarting your node? ---

Hi @Patrycjusz , We will investigate the issue. Can you provide the final fuel-core logs that you got before the node stopped? ---

> [@Patrycjusz](#): > > WARN fuel\_core\_upgradable\_executor::executor: 407 First of all, I would suggest upgrading to `fuel-core 0.30.0`. The warning itself is not harmful. We need other logs(in most cases error logs) which will describe the problem. ---

You can download new binary from release itself: [Release v0.30.0 · FuelLabs/fuel-core · GitHub](https://github.com/FuelLabs/fuel-core/releases/tag/v0.30.0) Or build a new from sources by using Rust: `cargo install fuel-core-bin --features production` ---

try update but have this error error: failed to compile `fuel-core-bin v0.30.0`, intermediate artifacts can be found at `/tmp/cargo-install3pJxof`. To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path. ---

@xgreenx Basically following official guide I also face with node stop syncing after few hours you suggest to upgrade fuel-core but why don’t you put the proper version into your guide? ---

since cargo update doesn’t work I’ve tried to update from github binaries wget [https://github.com/FuelLabs/fuel-core/releases/download/v0.30.0/fuel-core-0.30.0-x86\_64-unknown-linux-gnu.tar.gz](https://github.com/FuelLabs/fuel-core/releases/download/v0.30.0/fuel-core-0.30.0-x86_64-unknown-linux-gnu.tar.gz) tar -xvzf fuel-core-0.30.0-x86\_64-unknown-linux-gnu.tar.gz mv fuel-core-0.30.0-x86\_64-unknown-linux-gnu/\* /root/.fuelup/bin/ that’s what I did but fuelup show still says fuel-core is 0.26.0 but fuel-core -V fuel-core 0.30.0 ---
