can't update klipper and moonraker

[marcert]

Hi,
if I see on my hurakan the update manager it shows me that the OS is up-to-date as also mainsail (v.2.7.1). But klipper (v.0.11.0-271-g5f990f93) and moonraker (v.0.8.0-138.-gfe120952) is shown as corrupt. In the drop-down is the "hard-recovery" button but this does not work:
19:19:29 | Git Repo klipper: Attempting Repo Recovery... 19:19:29 | Git Repo klipper: Starting Clone Recovery... 19:19:29 | Cloning into '/home/biqu/.klipper_repo_backup'... 19:19:32 | fatal: unable to access 'https://github.com/Klipper3d/klipper.git/': Failed to connect to github.com port 443: No route to host 19:19:32 | Git Repo klipper: Git Clone Failed 19:19:32 | Error Recovering klipper 19:19:32 | Git Clone Error
If I use ssh to login to the hurakan I cannot even ping an external host- IP adress will be resolved but then I get "Destination Host Unreachable" although my network is working.

How to fix that?
Thanks!
