Have a nice day.
in the confirmation email there is an error.
the url is to confirm erroneous .. it is only the localhaost/xxx
but it would be the url from the config.josn ..
So he sends me to confirm link : http://localhost:4567/confirm/fa2044ba-37e0-4698-b758-843ad609adbf
but it would look like this : http://humanistischefriedenspartei.de:4567/confirm/fa2044ba-37e0-4698-b758-843ad609adbf
