Issue description

A brief description of the problem. Should include what you were attempting to do, what you did, what happened and what you expected to see happen.

Majestic doesnt reload properly when receiving the kill -1 HUP signal. It is my understanding that whenever a config value is changed i the HUP signal is sent and majestic reloads.

No changes have been made to replicate this issue. Default majestic.yaml config. Send kill -1 and it will not load again. Some majestic web UI pages (port :85) will show 500 Internal Server Error

All works fine on first boot.

Expectations

Majestic to successfully reload on config change/ HUP signal

Steps to reproduce

1. Step one Boot camera

2. Step two get PID from ps aux | grep majestic

3. Step three Send HUP signal with kill -1 <PID>

4. Step four Load a Majestic settings page on webUI port 85 and see 500 Internal Server Error

Information to attach

• [ ] Any relevant log output (logread -f)

Running killall majestic and manually starting mjaestic in the foreground. Then sending kill -1 signal from another window shows these logs:
