@JuergenAuer Thanks for the reply. I did notice the error message. It's just very strange that the other certificate which are installed on the server, have no problems.
@Osiris i removed the output for the other domains which do not require renewal
# /usr/local/letsencrypt/letsencrypt-auto renew

IMPORTANT NOTES:
- The following errors were reported by the server:
Domain: shop.agit-global.com
Type: dns
Detail: No valid IP addresses found for shop.agit-global.com
I suppose the last line ("No valid IP addresses found for shop.agit-global.com") is the culprit here. I had the same problem the last time I originally tried to issue a certificate for this domain:
The registrar for this domain is a Taiwanese company. Not sure if this has something to do with it...
