TEDPro 3rd Party Activation Not Working

I'm trying to set up a 3rd party server.

XML for activation:
<ted5000ActivationResponse>
                <PostServer>192.168.0.221</PostServer>
                <UseSSL>F</UseSSL>
                <PostPort>5000</PostPort>
                <PostURL>/post_readings</PostURL>
                <AuthToken>1234</AuthToken>
                <PostRate>1</PostRate>
                <HighPrec>T</HighPrec>
                <SSLKey>NOT IMPLEMENTED</SSLKey>
</ted5000ActivationResponse>

I keep getting a timeout from the TEDPro. It's sending a successful response to the activation post with the above payload.

Stats page shows this:
3rd Party Post

0   0   0   0   0   0   192.168.0.221:0   /activation

0   0   0   0   0   0   192.168.0.221:0   /activation

The data I'm entering in the activation page is this:
http://192.168.0.221:5000/activation
1234

I can see the POST hit my server, I know what my response is, but the TEDPro doesn't seem to want to take it.

I've rebooted several times.

Any suggestions? I'm out of ideas.

Thank you in advance.
