LetsEncrypt Certificate not auto renewing

[Richard I]

Hi all,
While I can successfully, manually renew the Certificate from the template, the last auto renewal failed.
At the time the exe was running as a Service, so I stopped that and updated from the web serever.
The app is running from an Amazon Server.

I have checked the settings and the paths appear to be correct.
I attach a snip

Is there are reason?

Thanks

I have always had this problem when it runs as a service and i have never found a solution, even when i have an account assigned with administrator privileges to the service.
