I have previously used Formidable with no issues on Zapier. When I was recently trying to edit the forms, I found that they were not pulling the most recent changes in Formidable. So I did a basic reconnect, and it was still not working. I then flushed cache on Wordpress, disconnected Formidable from Zapier, and attempted to re-connect it.

When I attempted the reconnect, I began getting the API error code issue. I then went through ALL of the troubleshooting options advised at the Zapier/Formidable troubleshooting page suggested, with the same results.

My host runs NGINX servers, and that Basic Authenticate is on by default in Privacy Mode, although I'm not sure what that entails, so I have opened a ticket with them to describe that in more detail. On NGINX servers there is no .htaccess that can be edited, but that is the only option I'm unable to troubleshoot based on the instructions that could be an issue - however there was no issue previously until I attempted the disconnect/reconnect.

I have also removed the Formidable plugin (including the Zapier plugin for Formidable) and re-installed them, generated a new API key and it did not work. I eliminated every plugin that was not necessary to the site and I’m not running anything that isn’t core to WP or my website builder. When I attempted the Postman troubleshoot, it did not work, and just I tried using the API key at the end of the trailing url - at that point I started getting a 404 error, but I'm not sure where to go from there, as there is no documentation.

Again, the connections were working fine before I started doing edits and attempted a re-connect, so it was working with my host. I have not made any other changes, added any plugins or done anything in Wordpress that would have affected Zapier or Formidable.

Any help would be appreciated!
