Proetheus - Back-off restarting failed container

Hello Folks, I am trying to integrate alert manager with Jira, so that every alert is creating a ticket. I got this GitHub repo https://github.com/prometheus-community/jiralert for jiralert. I want to deploy it on AKS, got the files here - https://gist.github.com/erdii/8db7b5a6356c3d5e023b985b6febd57c . However creating pod is showing “Back-off restarting failed container” error. Any idea what can be done to resolve this.

Check the pod logs. any errors?

These are the logs, any idea what needs to be change?
