Dose self-hosted NewsBlur support BlurBlog?

I have setup a latest NewsBlur on a cloud VM. And set the custom domain to aaa.bbb.xyz.
But I tried MyUserName.aaa.bbb.xyz it’s redirect to the homepage of my self-hosted newsblur.
(I have bind both aaa.bbb.xyz and *.aaa.bbb.xyz to my VM ip)

So, my question is that dose the self-hosted version support the BlurBlog.
If yes, what should I do to enable it?

You’ll need to work with the haproxy config and nginx config. It won’t be trivial to support a domain like that but it’s not impossible. Look for haproxy.docker.conf and the same for nginx.
