Can‘t reinstall mac os x during recovery

Hi everyone, hope you‘re doing better than me :)

After previously patching my 2011 mac to Sequoia and having it run beautifully, I made the mistake of keeping it on standby for too long which seems to have caused an issue, the progress bar got stuck and the computer wouldn’t start up again (not sure what could’ve caused that).

So I decided to do another erase and install in an effort to get it running again. Unfortunately I‘ve run into an issue I‘ve never had to deal with before, an error message stating that the necessary additional components to reinstall mac os x (pressing cmd r) and high sierra (pressing cmd alt r) can‘t be downloaded.

Internet connection is solid, harddrive was deleted and partition set to mac os journaled.

Any ideas on how to resolve this to get to the next step of this headache? Thank you :)
