I'm trying to test out connecting to a Wordpress dev blog (that is behind our firewall) and on a different server than the one where Squiz Matrix is hosted. I've connected up the proper REST API JSON feed that is generated.
Problem is that I am receiving this error on the bottom of the details screen when I tried to get it to grab the JSON data (in the Raw Source Data area:
Forbidden You don't have permission to access /jol/wp-json/wp/v2/posts on this server.
I can access the JSON data no worries from the URL in a browser window. Am I having issues because it is behind a firewall and Squiz Matrix just does not like it? I have tested this out on my own public blog (not behind a firewall) and it works fine.
