Composer – Download Failed, Retry … Download from https://repo.magento.com/archives/magento/magento2-base/magento-magento2-base-2.3.0.0.zip

I have to say, it is really hard and sad. Normally, nothing works the way it should if you follow the official step-by-step instructions.

For a few hours or better days I try to install Magento2 via Composer.
Actually, it hangs up while all the packages are downloaded.

The biggest, I think, is the Magento2 base …

When the download is almost 100% done, I get "code" like this:

Download failed, it will try again ...

Download (xx%)

The download is restarted … several times but no way to get the package.

After a few issues that I've faced, it looks like the Magento repo server has some connection issues. This seems to be the toughest nut.
Has anyone ever had such problems? In the best case exactly this error?

Thanks for your help.
