Certbot Renew Fails when in Crontab but not when typed in?

I have the below command in crontab.

it fails.

when I run it at the command prompt as ‘certbot renew’ it completed successfully.

any ideas? running in the root crontab.

My domain is: nomorestars.com

I ran this command: /usr/bin/certbot renew --quiet --preferred-challenges http

It produced this output:

Hi @trekkie

that’s a typical problem if crontab has other path definitions.

Use crontab -e to edit, add something like

PATH=/sbin:/bin:/usr/sbin:/usr/bin

to add a path.

Use the result of your interactive, working version.
