My device architecture is arm-v7, Linux 3.10.  
I used to download Docker based Node-red using the following command in 2023, but it doesn't work now:

root@SMT-ECUa11:~# docker run -v /node\_red\_data:/data --group-add dialout -p 1880:1880 --privileged=true --device=/dev/ttySZ3 --device=/dev/ttySZ4 --device=/dev/ttySZ5 --device=/dev/ttySZ6 --name mynodered -u root:dialout -e TZ=Asia/Shanghai nodered/node-red

Unable to find image 'nodered/node-red:latest' locally  
docker: Error response from daemon: Get [https://registry-1.docker.io/v2/:](https://registry-1.docker.io/v2/:) net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).  
See 'docker run --help'.
