Non UTF-8 Domains are unsupported


I tried to setup an ssl cert for www.ü.de that can commonly be called as www.uٙ.de
The first is a problem because UnicodeEncodeError: ‘ascii’ codec can’t encode characters in position 24-25: ordinal not in range(128) that’s ok
The second Error: unauthorized :: The client lacks sufficient authorization :: Error creating new authz :: Syntax error Please see the logfiles in /var/log/letsencrypt for more details. even if it’s whitelisted


Please use search
Try these terms:
Internationalized Domain Name



Thanks for your info


question is, did you try the IDN or the Punycode (xn) variant?
