Installation fails: FAILED: wget -O /tmp/z-push.zip https://stash.z-hub.io

I was trying to instal MiB but I have the following error with Z-Push:

I tried a solution found in the forum to add the IP in /etc/hosts (195.201.215.164) but that doesn’t seem to work anymore.

Please fix this.

Kind regards,
