I have my grandads old iMac and I have erased the HD in recovery mode to reinstall the os (seems to be Yosemite). When i try to sign into the App Store to reinstall I get an error every time that says ‘the server gave an error during download: 403 forbidden.
any idea what I can do?

Do you have another Mac available to you? You need to make a bootable installer:
Create a bootable installer for macOS - Apple Support
I believe you can still get the Yosemite installer from Apple:
And the command line instruction from the bootable installer instructions should work if you just substitute "/Applications/<the actual path to your Yosemite installer>" for "Applications/Install\ OS\ X\ El\ Capitan.app"
But don't feel like you have to reinstall Yosemite - either of the 2014 iMac (early 2014 slim unibody or late 2014 retina) can run up to macOS Big Sur.
Thank you very much. I do have another Mac. I will get a usb stick and create a bootable drive.
