About linux : Setting-up-Prometheus-on-Linux-as-a-service-resulting-in-codeexited-status2

I am trying to setup Prometheus as a service on Linux to monitor external Linux nodes. However I design the systemd service (on my monitor node) seems to fail. My OS is Ubuntu 20.04.3 LTS and I’m runing Prometheus version prometheus-2.31.1.linux-amd64.

My systemd service is setup like this:

    [Unit]
    Description=Prometheus Server
    Wants=network-online.target
    After=network-online.target
    Requires=prometheus.service

    [Service]
    User=usr
    Group=usr
    Type=simple
    ExecStart= /home/usr/Downloads/prometheus-2.31.1.linux-amd64/prometheus --config.file=/home/usr/Downloads/prometheus-2.31.1.linux-amd64/prometheus.yml
    
    
    [Install]
    WantedBy=multi-user.target

When I try to run the service manually I get the following error:

prometheus.service - Prometheus Server
     Loaded: loaded (/etc/systemd/system/prometheus.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Sun 2022-01-02 18:50:38 CST; 17min ago

Jan 02 18:50:38 monitor systemd[1]: prometheus.service: Failed with result 'exit-code'.

Can anyone help me to understand where I am going wrong? The user has permissions to execute all the files and I have tried adding new user profiles just for the service with little success. Any help on better diagnosing the issue or possible fixes would be greatly appreciated.
