Hi Hugo,
I think I found a bug in hiawatha lets encrypt:
If I have an comment behind my Webroot in config, Now I cannot renew my cert...
WebsiteRoot = /webroot/abc # lorem ipsum
If I renew my cert, the folder "/webroot/abc # lorem ipsum" is created, but letsencrypt gets an 404 error, cause hiawatha uses /webroot/abc and not "/webroot/abc # lorem ipsum"...
