OK, I just did the following on a v9.x box
[root@photos ~]# yum --enablerepo=reetp update
[root@photos ~]# signal-event post-upgrade; signal-event reboot
[root@photos ~]# rpm -qa |grep letsencrypt
letsencrypt.sh-0.0.9.160803.gitafabfff-1.noarch

Here's my asterisk v9 box - it threw errors twice and then resolved:

The Cert looks like it was dated 14/7/2016 (you can view it at the site)
The only things I can guess at (and I am no expert on this) is that the letsencrypt.sh script has changed a bit as you can see from the output above and I wonder if any of those changes have had an effect - you may need to use -x the first time after the update.
Whether it is an issue with letsencrypt servers, or an issue with Koozali SME server I do not know.
