Wordfence conflicting with PilotPress causing an error

I installed the free version of Wordfence on a client’s website. When I try to run a scan I get this error:

wp_remote_post() test back to this server failed! Response was: 200 OK

I did some troubleshooting and found that when I deactived the PilotPress plugin, I had no issues with Wordfence. I could scan just fine. When I turn PilotPress back on, I get the error again. This is an established website and deleting PilotPress is not an option. How can I fix this and get Wordfence to work??
