XMLRPC error message "Unable to get ip id by address from db" when adding domains

[GrahamW]

I'm getting the following response from the server:

<packet version="1.6.0.1">
<domain>
<add>
<result>
<status>error</status>
<errcode>1023</errcode>
<errtext>Unable to get ip id by address from db</errtext>
</result>
</add>
</domain>
</packet>

after attempting to add a new domain on an existing shared IP address on the server.
I have checked and confirmed that the IP address is valid, in the system, and it the same as is returned when I send a packet off to query for available IPs.

Any help on tracking down this issue would be helpful. Thanks.

Try to reread IPs on this Plesk server and make sure that this IP is really exists in client's IP pool.

I have reread the IPs, and confirmed they are correct and valid.
The user I am using to test the XMLRPC API is the admin user. How do i get this IP address included in the admin users IP pool?

 

[GrahamW]

I have refreshed the IPs, and confirmed the set are valid.
Current testing is using an administrative user for connection via the API.
Do the IP addresses need to be assigned to a pool for this user in order to correct this error message?
