CSF Blocking/Throttling Infinite WP on port 80

[TBLHosting]

Hi All,

I'm running into a strange issue where CSF is throttling or blocking Infinite WP (A wordpress plugin/theme manager).

IWP uses ajax requests to check on plugin status as well as updates them.

When I watch the access_log for apache, I see a lot of AJAX requests.

If I have CSF on, most of them time out, usually 2/22 get through.

However, if I turn off CSF, they all go through, and fast.

Any ideas as to what setting in CSF is causing this?

I've whitelisted my IP in .ignore and .allow as well as the server's public IP.

Thanks.

The IWP is hosted on the same server CSF is installed on.
