Patch manager SCCM integration

I appear to be stuck configuring Patch Manager. I had set up Patch manager on Server A and have our SCCM server on Server B. I've installed Patch Manager Admin console on the SCCM server and pointed the Update server and Configuration Manager to point to Server B. All looks great so far. I've decided to publish a Chrome update but can't seem to get it distributed from our SCCM.  Our SCCM SUP pulls from Microsoft Update server, so I presume that may be the issue unless there's something that I had configured wrong. Thank you!
