[Bug] Failure to download 2stems.tar.gz

[all-the-good-ones-are-gone]

• [x] I didn't find a similar issue already open.
• [x] I read the documentation (README AND Wiki)
• [x] I have installed FFMpeg
• [x] My problem is related to Spleeter only, not a derivative product (such as Webapplication, or GUI provided by others)

Description

Yesterday and today, running the docker container results in error message that model was not found to download.

Step to reproduce

1. Installed using docker pull researchdeezer/spleeter

1.a. pull now results in Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on 10.0.2.3:53: read udp 10.0.2.100:44489->10.0.2.3:53: i/o timeout

2. using existing container, running docker run -v ~/Spleeter/output:/output -v ~/Spleeter/input:/input researchdeezer/spleeter separate -i input/* -o /output -p spleeter:2stems -d 7000
3. Got

Additional context

I had the same issue with the 4stem version as well working locally on my Mac Mini.

A temporary workaround is to manually download and unzip the model files from https://github.com/deezer/spleeter/releases/download/v1.4.0/2stems.tar.gz and place them in the pretrained_models directory.
