Could not connect to the remote site.

[beemerrider]

I have 24 sites successfully added to Panopticon, mainly Joomla and a few WP sites all working great. I have two Joomla sites I cannot connect to though. All sites are on the same dedicated server. No MOD security rules are being tripped. Setup on Joomla sites with firewall, SEO, etc, are all similar. I have rebuilt the htaccess file with Admin tools. There is no record of the firewall blocking the request. Below is the debug info:

Could not connect to the remote site.

Instead, we got an error which we should be able to provide troubleshooting information for (Akeeba\Panopticon\Exception\SiteConnection\APIApplicationIsBroken), but we don't have the code for it. This should have not happened.

Please delete all files and folders inside the tmp folder of Akeeba Panopticon. This addresses the problem of this page's cached copy being severely out of date. If this doesn't help, please let us know.

Have you activated the error display? I get the same error.

On my website the plugin “ChronoG3_Plg” as part of the component “Chronoforms 7” seems to cause the HTTP 500 error:
Error: Class "G3\L\AppLoader" not found in /var/www/vhosts/www/plugins/system/chronog3_plg/chronog3_plg.php:111

Deleting the files in the tmp folder did not help.
