I have an server with centos7 and nginx web server with 3 domains. I create Let’s encrypt SSL without problem for them, and have renew all SSL one time, the next month, with and simple script :
/usr/sbin/nginx -t && service nginx reload
But now I always have the same error when I try to use this script :
Renewing an existing certificate
Performing the following challenges:
http-01 challenge for XXXXX.net
http-01 challenge for www.XXXXX.net
Using the webroot path /var/www for all unmatched domains.
Waiting for verification…
Cleaning up challenges
Attempting to renew cert from /etc/letsencrypt/renewal/XXXXX.net.conf produced an unexpected error: ‘ascii’ codec can’t encode character u’\xe1’ in position 250: ordinal not in range(128). Skipping.
