Publish to local network problem

Problem publishing on my private internal network.

Sparkle 2.8.3
MacOS High Sierra, apache enabled

While I cannot publish the site successfully using the Sparkle tool, I have copied it into the default location and can view it at the local IP address from any location within the network.

The publish setup is

Web address
Connections 1-Most Compatible
Protocol Autodetect (have tried all the others as well)

So I’m sure my problem is with the address string, but I have many permutations with no success

Also, the Help manual refers to an intermediate screen to suss out the filepath. This screen does not popup for me when the Publish tool fails.

Thanks for all advice.

Please share a screenshot of the error Sparkle shows, or we can continue privately if you prefer:
