Hey folks, we have received reports of Arbitrum Sepolia node operators failing to sync the chain with errors relating to validating the feed signature. We've disabled feed signing on Arbitrum Sepolia as a remedy while we root cause the issue and work on a fix. Arbitrum Sepolia nodes on 3.7.6 should now be healthy again. If you are running an Arbitrum Sepolia node on 3.8.0 (on any rc), your node will gracefully shut down and so action is required to restart your node with the following flag in order to get your node syncing again with Arbitrum Sepolia. --node.feed.input.verify.dangerous.accept-missing We will continue our investigation and will cut a new release shortly. Thanks for your understanding and patience.
