This is a correct link https://blog.npub.pro/post/how-to-self-host-on-github Can you tell where you got the wrong link, please?
On the main npub.pro page under the "Can I self-host?" section, the "read more here" link resolves to the original link I posted.
Oh thanks a lot, fixed!
np and thanks for rapid fix! npub.pro is an awesum tool.
