🐞 Bug Report

Description

Validators throwing the below errors and causing the earning to drop to close 0% on the hourly tracker.

Has this worked before in a previous version?

This seems to be intermittent as I upgraded my node to alpha.24 today. ## 🔬 Minimal Reproduction No special changes between alpha.23 vs. alpha.24. ## 🔥 Error

This may just be a temporary down time whether it is your internet or on the remote.

Does this link work for you? caesium.tannerryan.ca

@terencechain - The link is working for me. It's probably just a hiccup from the ISP in my area. Thanks.
