How to link a webflow CMS Site to a domain's subpage

I’m building a webflow site known as our ‘Learning Hub’ - with a bunch of subpages like /blog, /podcasts, etc.

We’ve connected it to a subpage on our main site:

Our connect is successful for the main page ( however whenever clicking to go to a subpage from, it is breaking the URL and instead of going to “” it just tries to go to “” which doesn’t exist.

We have tried to put in the head of our pages, and that didn’t work.

As I’m told, the problem is the link needs to go to “blog” not “/blog”

Can anyone advise, please.
