I have certbot installed on my server and things running smoothly until today when suddenly the SSL stopped working. When I did
letsencrypt renew from the command line, I got:
2017-04-24 04:24:20,037:WARNING:letsencrypt.cli:Attempting to renew cert from /etc/letsencrypt/renewal/domain.com.conf produced an unexpected error: urn:acme:error:rateLimited :: There were too many requests of a given type :: Error creating new authz :: Too many invalid authorizations recently.. Skipping.
Now, there has been no login into the server in the past month or so, and things were running smoothly. I wonder what went wrong. The only oddity I can point to is my crontab, which reads:
* * * * * letsencrypt renew
Could that be the problem? Either way, how come there are invalid authorizations?
