Patch Management - Error: Could not connect to the HTTP server to download (null)

[CCNapier]

Looking at a specific patch management policy log, an attempt to install shows:

Error: Could not connect to the HTTP server to download (null)

It seems like the package name isn't being interpreted correctly. Any idea on best way to try and fix this?

Seems like it might be because my IIS certificate expired!
Which leads to another question (maybe I should repost):

Why isn't the patch downloading reverting to the failover connection?
Failover is setup, and policies revert to failover OK.

So yes, IIS cert updated and now working, connects OK.
Support says fallback is not supported at the moment, but a feature request is active.

Hello,

What is IIS cert? Where can I confirm if I have this cert?
Thanks,
