QRadar: Could not retrieve "manifest_list_512": 500 Can't connect to 127.0.0.1:443 Could not download manifest list.

While installing autoupdate package on an offline environment, I got this error message:

Could not retrieve "manifest_list_512": 500 Can't connect to 127.0.0.1:443 Could not download manifest list.

For solution I set the hostname as QRadar dns name and I test connection with:

[root@qradar autoupdates]# /opt/qradar/bin/UpdateConfs.pl -testConnect 1 0

command.

Recently, I was trying to use Install-Module cmdlet to install a required module for some testing on a client machine however I ran into the following error

The error looks like below:
