Spoolman doesn't start on Raspberry Pi4

[Fenris1983]

Hello, I installed Spoolman on a new Raspberry Pi4 with 32 bit OS with the given comma:

sudo apt-get update &&\ sudo apt-get install -y curl jq & \ mkdir -p./Spoolman &&\ source_url=$(curl -s https://api.github.com/repos/Donkie/Spoolman/releases/latest | jq -r '.assets[] | select(.name == "spoolman.zip").browser_download_url') & \ curl -sSL $source_url -o temp.zip && unzip temp.zip -d./Spoolman &&rm temp.zip &&\ cd./Spoolman && \ bash./scripts/install_debian.sh

Unfortunately, Spoolman doesn't start. Only the error message "ERR_CONNECTION_REFUSED" appears. What could be the reason for this?
