Hi there,
I just moved this thread to “How to” category as it’s not a bug in Bricks.
This error message is more to your server SSL configuration.
Unfortunately, we don’t have a clear idea of what causing the issue.
It would be best if you could check with your server/hosting support and let them know your environment is unable to make wp_remote_post() request to your own domain name which will be used when using Bricks Query Filters feature.
Regards,
Jenn
