(feature request) - Better error handling

[lightnode]

Summary

When syncing Zepio from ~95%, I was presented with the: "Zepio could not find a daemon running, please check the logs" error message. Now, I knew it was probably because I needed to update, but I wanted to check the logs just to see what they said, but I had no idea which ones or where they be.

Motivation

My main question is what can be done to improve the UX when this happens? A link to the logs? Better instructions? Is there a way to pull the info from the logs and state the problem with more specificity?
