as suggested by the pop-up dialog window, you should read the log file generated during the netlist extraction.
The message says that there is a connection problem at x: 107, y:34, layer: 0. Just go with your mouse cursor over the correct coordinate and check if you have properly connected the pNML elements.
For the available connectivity, please have a look at the documentation.
In case you still have problem please upload the layout file and not the screenshot.
