Hi Ukusic.
The plugin can return only up to 1000 IPv4 networks and up to 1000 IPv4 ranges from NIOS per one request.
When you click on "+ Add" button, the plugin tries to return all IPv4 networks and ranges from your NIOS server.
But it looks like the number of IPv4 networks or ranges in your NIOS is more then 1000, and you get the error "Result set too large (> 1000)".
The way how you can try to limit the number of networks/ranges in this case - choose appropriate Address Space (Network View in terminology of Infoblox NIOS) first and then click on "+ Add" button.
In this case the plugin returns IPv4 networks and ranges only from selected Address Space (Network View). If the number of networks/ranges in selected network view will be less than 1000, everything will be OK.
Take into account that if you don't choose any Address Space on this page (as I can see at the screenshot you attached), the plugin will try to return ALL IPv4 networks and ranges from NIOS and the probability to face with "Result set too large (> 1000)" is higher in this case.
Another way - open a ticket with Infoblox Support, as it was suggested above.
Looks like the issue on the plugin side.
Best regards,
Alex
