.htaccess auth failed

[OliverTempel]

I run the following code:
docker run -it -d \ -p 4080:8080 \ -p 53:53 \ -p 53:53/udp \ -v /opt/ddns/bind:/var/cache/bind \ -v /opt/ddns/database:/root/database \ -e DDNS_ADMIN_LOGIN='******:$$apr1$$evkvf9PG$$q6yyhxZvWdtPN5Vmg1Mne/'\ -e DDNS_DOMAINS=dyndns.*****.de \ -e DDNS_PARENT_NS=dns1.*****.de \ -e DDNS_ALLOW_WILDCARD=true \ -e TZ=Europe/Berlin \ -e VIRTUAL_HOST=dyndns.olivertempel.de \ -e LETSENCRYPT_HOST=dyndns.olivertempel.de \ -e LETSENCRYPT_EMAIL=info@olivertempel.de \ -e DDNS_DEFAULT_TTL=3600 \ --network="proxy" \ --name=dyndns \ bbaerthlein/docker-ddns-server:latest

username and password where generated with:
echo $(htpasswd -nb user password) | sed -e s/\$/\$\$/g

If i want to login, it says authentication failed.

Whats Wrong?
