[BlueOnyx:22390] Let's Encrypt failed notices

[Robert Fitzpatrick]

This morning I received failed notices from two separate 5209R servers. For
the admserv on one and a vsite on the other. Both say to check
/var/log/letsencrypt/letsencrypt.log for more information. But both of the
logs are empty. How can I find out what went wrong?
