More than likely it's a system permissions issue with your volume mapping. NxFilter runs with root privileges in the container to be able to bind to the TCP and UPD ports required. Java may also but I'm not sure of that one. For my Debian 11 test system, I use this docker compose which maps the volumes to /var/lib/docker/volumes/compose_nxf* The file owner/group in the _data directories there are a mix of root and my personal user.
