How to handle a 404 error message from Google Search Console?

[RyanB2]

Hi all,

i had a message from google search console to say page couldn't be indexed: page not found 404.

it was this page but I didn't even know it exists, because it's not on my site, whats the best thing to do here, I don't need or want the page but i don't want it to affect my google ranking because google can't find it.

Thanks for your help

Ryan
