cURL error 7 // Same server

Hello,

i installed collabora on the same device as nextcloud is running. But unforunatelly i don’t get it work.
I get this error: GuzzleHttp\Exception\ConnectException: cURL error 7: Failed to connect to xx-office.dedyn.io port 9980: Connection refused (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

Docker is running and was installed with: docker run -t -d -p 127.0.0.1:9980:9980 -e 'domain=xx-office\\.dedyn\\.io' --restart always --cap-add MKNOD collabora/code

Any idea what i made wrong?

    <VirtualHost *:443>
    	ServerName xx-office.dedyn.io
    	ServerAlias office.xx.com
