[mattsse]

Describe the feature

this currently fails in CI

reth/crates/cli/commands/src/stage/run.rs

Lines 192 to 194 in f2bf024

	let tip: P::BlockHeader = fetch_client
	.get_header(BlockHashOrNumber::Number(self.to))
	.await?

if we lose the connection to the peer, in which case we should retry the request indefinitely

TODO

reth/crates/net/p2p/src/error.rs

	impl RequestError {
	/// Indicates whether this error is retryable or fatal.
	pub const fn is_retryable(&self) -> bool {
	matches!(self, Self::Timeout | Self::ConnectionDropped)
	}

On it, few qns @mattsse

• should I just use loop or backon retry which seems to be used at other places ?

  reth/crates/cli/commands/src/p2p/mod.rs

  Lines 120 to 123 in f2bf024

  	let header = (move || get_single_header(fetch_client.clone(), id))
  	.retry(backoff)
  	.notify(|err, _| println!("Error requesting header: {err}. Retrying..."))
  	.await?;

• no. of retries and any interval b/w them ?

[mattsse]

for this we can just loop, this is simple enough
