I don't get it. I am not getting the crontab for letsencrypt to work. Every 3 months another try and I need to do it again "by hand".
I have the crontab:
45 20 * * * /usr/bin/certbot renew >> /var/log/letsencrypt/renew.log
The certbot renew does not run through.
If I log in as root and run the command /usr/bin/certbot renew by hand then the certificates get renewed without a problem.
What needs to be different in the crontab?
