A few issues in MAAS

Hi,
I have some few issues that find out docs are not useful at all.
I have installed MAAS via snap and it is fine but so far I have got a few problems that could not solve them.

First, I have created local mirror which does not work with the following url.
http://10.10.9.60/maas/images/ephemeral-v3/stable/

it says refuse to connect.

Second, cento7 image is stuck in the following state.
Waiting for rack controller(s) to sync

@sysnasri, hey, did you ever resolve this?
