JCI Shortcode sometimes stops page from loading

Hi,
I’m using a jci shortcode on one page of my site and sometimes that page stops loading when it reaches the JSON call. The default error message doesn’t display and the rest of the pages html doesn’t load, even if the page is refreshed or launched in different browsers.

To resolve the issue I have to log into wordpress and view the page while logged in to get it back online. After that it loads perfectly with no issues.

I’m not using plugin caching, my settings are mostly all default and there are no plugin conflict issues. The hosting provider is WP-Engine and they do provide some page level caching by default but do a pretty good job with plugin compatibility.

Here is my short code below:
[jsoncontentimporterpro url=https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quote%20where%20symbol%20in%20(%22MSFT%22)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&format=json id=1 parser=twig]

The strange thing is it doesn’t happen that often and I cant find a way to replicate the issue. The next time it happens I am going to put the plugin in debug mode and refresh the page before I log in to see if I get any output but I cant find anything in my error logs either.

If anyone has any ideas on how to troubleshoot this issue it will be greatly appreciated!

Thanks!
