FS Contact Form Redirect Hanging

So far, for 9 minutes…

I have version 3.1.7.2 of FS Contact Form. The redirect is not redirecting yet as I’m watching it right now and my client said that it took her 5 minutes. I don’t recall having a redirect issue in the past with FS Contact Form… at least not this long of a redirect. What could be causing this?

– The redirect URL is a full address such as https://
– I am posting no data, simply sending an email with some of the extra fields and redirecting
– Email sending works
– No theme conflict (tested)
– Plugin conflicts (tested all but HTML page sitemap, Ultimate TinyMCE, and wordpress page widgets).

Is there anything else I should be looking at? Hosting / permissions or ??

Thank you very much for your input.
