Webfs - cannot change document root

Code:#uname -a
Linux fir.nuclix 5.3.0-3parrot3-amd64 #1 SMP Parrot 5.3.9-3parrot3 (2019-11-23) x86_64 GNU/LinuxCode:#webfsd -h
-r dir document root is >dir<

#webfsd -r ~/webdocs
bind: Address already in useCode:# vim /etc/webfsd.conf

# document root
web_root="/home/myhomedir/webdocs"

#service webfs stop
#service webfs startFails again. It still uses /var/www/html as the document root.

Any ideas?
