Hi 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 : /root/letsencrypt/letsencrypt-auto renew /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://XXXXX.net) http-01 challenge for [www.XXXXX.net](http://www.XXXXX.net) Using the webroot path /var/www for all unmatched domains.

> [@configbox](#): > > 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) This is the key part. There is an invalid character in that file. can you check the file ? alternatively can you paste the full file in [pastebin.com](http://pastebin.com) or somewhere so we can review it ? ---

if you refer to /etc/letsencrypt/renewal/XXXXX.net.conf file, the contain is this one (Sorry, I prefer hidden real domai name by XXXXX, but no special char in it) # renew\_before\_expiry = 30 days version = 0.9.3 cert = /etc/letsencrypt/live/XXXXX.net/cert.pem privkey = /etc/letsencrypt/live/XXXXX.net/privkey.pem chain = /etc/letsencrypt/live/XXXXX.net/chain.pem fullchain = /etc/letsencrypt/live/XXXXX.net/fullchain.pem # Options used in the renewal process [renewalparams] authenticator = webroot installer = nginx account = 7ef54115e4f79a2b8780ecca13b9efa4 server = [https://acme-v01.api.letsencrypt.org/directory](https://acme-v01.api.letsencrypt.org/directory) webroot\_path = /var/www, [[webroot\_map]] [XXXXX.net](http://XXXXX.net) = /var/www [www.XXXXX.net](http://www.XXXXX.net) = /var/www ---

The problem is, as soon as you edit it - then the special char will probably get removed. hence asking for you to paste the complete file. I suggested pastebin, as that can be pasted for a limited amount of time, and then removed ( say 15 mins ) ---

> [@serverco](#): > > pastebin Ohhh, I have found the problem... None of the vhosts have the ".well-known/acme-challenge" correct config, so they will return to 404 page that give the ascii error! Putting the correct config ( location ~ /.well-known/acme-challenge { root /var/www; } in our case ) all work! Thanks a lot serveco, with your answer I discover the problem! ---
