Impossibility to add zigbee2mqtt (github) into HA apps

Hello everybody,
I have installed HA on a minipc.
everything goes well so far.
I received my dongle zigbee, that I flashed with latest firmware.
I would like now to install the zigbee2mqtt app, what I did (following tutos):

Cmd('git') failed due to: exit code(128) cmdline: git clone -v --recursive --depth=1 --shallow-submodules -- https://github.com/zigbee2mqtt/hassio-zigbee2mqtt /data/addons/git/45df7312 stderr: 'Cloning into '/data/addons/git/45df7312'... fatal: unable to access 'https://github.com/zigbee2mqtt/hassio-zigbee2mqtt/': Failed to connect to github.com port 443 after 2761 ms: Could not connect to server '

can someone help me with this error? thank you!
