Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA

问题

I've been following this tutorial to add SSH Certification to my site. However at the moment this method does not work for the time-being due to a security flaw, so here is the alternate method. I'm trying to implement the alternate code-paste: sudo certbot --authenticator webroot --webroot-path <path to served directory> --installer nginx -d <domain> however am not sure what to put in <path to served directory>.

Is the "path to served directory" the nginx config? Would it look something like this: etc/nginx/sites-available/<projectname>?

You may have tried this already, but I found this to work, at least until an update is issued:

sudo certbot --authenticator standalone --installer nginx -d mydomain.com -d www.mydomain2.com --pre-hook "service nginx stop" --post-hook "service nginx start"

If you are on for debian/ubuntu and running apache this will work for you :

    sudo certbot --authenticator standalone --installer apache -d <yourdomain(s)> --pre-hook "apache2ctl stop" --post-hook "apache2ctl start"
