Impossible to download older macOS versions

I am trying to get the High Sierra download--though it doesn't work even when I use Safari.

How/where should I find the correct download for OS X High Sierra? I need to create a bootable drive for an older iMac.

This is what I have been trying without success:

https://apps.apple.com/us/app/macos-high-sierra/id1246284741?ls=1&mt=12

Thanks!

The link I get from the "How to Get Old Versions of macOS" Apple Support webpage is:

https://apps.apple.com/app/macos-high-sierra/id1246284741?mt=12

... and that link just leads me to a dead-end page that sticks forever saying:

Connecting to the Mac App Store

..

To use the Mac App Store, you need Mac OS 10.6.6 or greater. For more information, please click here

I am using a MacBook Air running macOS11.1... so that isn't the problem, and there is no High Sierra update available on the App Store anyway (at least not that I can find).

When I use the link you suggested in the other help thread (https://itunes.apple.com/app/macos-high-sierra/id1246284741?mt=12) in Safari my computer opens the software update window of the control panel and attempts to locate the update before giving this error:

Update not found. The requested version of macOS is not available

Thanks for the help!

Use ONLY Safari - FF / Chrome will Not work

It was a pleasure and Thank you for marking as solved. Do come back when more issue arise of juts to help someone else

And what are you getting?

I think Big Sur may be the problem, but...

Are you running any VPN, Anti-Virus, or Cleaning apps?

The Catalina, Mojave & High Sierra download links are not working. Temporary glitch perhaps.

Thanks. :)
