bitnami letsencrypt bncert lego logs

Question

I've been using bitnami-bncert to automatically renew the certs on my lightsail instance, and this normally works. But every once in a while it fails to renew. In crontab it appears that the /opt/bitnami/letsencrypt/lego is running once a day, and I can see that happening in /var/log/syslog.
But I can't find any output in any of my logs that would help tell what's failing.
Does anyone know if the "lego" command writes any logging or error information, and if so where can I find that?

I wasn't able to redirect the output (due to the complicated nature of the set of commands being used. It wasn't just the lego command). But I did eventually figure out that if I installed the mail utilities that cron would email me the output.

`sudo apt-get install mailutils`

I didn't actually realized that these tools were not installed by default or I would have done that a long time ago. Now the bitnami user is getting all sorts of useful information from cron :-)

It *appears* (from the message I'm getting) that renewing my certificate requires that http be enabled in the firewall (in addition to https). I did in fact turn that off at some point. So I've got that turned back on and we'll see if it renews tomorrow morning.

Hello.

Why not try redirecting the output of the command set in crontab as shown below?  
```
/opt/bitnami/letsencrypt/lego > /tmp/cert-renew.log
```
