SCCM client install failing, cannot get directory list

I am trying to install the client on my test box, SCCM-Test-PC. The host server is SCCM3 and they are on a domain called ArchPixm.

When installing, I get the following errors:

GetDirectoryList failed with a non-recoverable failure, 0x80004005 ccmsetup 12/8/2020 11:17:20 AM 100 (0x0064)

Failed to get directory list from 'http://SCCM3.ArchPixm.local/CCM_Client'. Error 0x80004005 ccmsetup 12/8/2020 11:17:20 AM 100 (0x0064)

I went onto the test box and tried to access the site directly from IE with no luck (connection refused error).

I made sure that port 80 outbound and all WMI rules were applied on the client box, and the same inbound on the server.

Anyone know how I can fix this?

I was able to bypass this by downloading the directory using WGET and running the installer manually. Obviously this is not a perfect fix to this problem and it wouldn't suffice outside of a very limited lab like I have, but it did fix the problem short-term.
