MGMT Cli with proxy

[HS]

Hi,

we create a R80.20 management on Azure Cloud and we need to backup the configurations to a blob storage account.

we found this sk https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut...

but there is no internet connections and we are unable to use proxy by cli. 

Do anyone have some idea how we can use proxy with cli ?

Than you very much for your replys
