Environment

VMware vRealize Network Insight 6.8

Cause

This issue is seen due of latency between collector and datasource and/ or between collector and platform appliances.

The recommended network latency between platform and collector VMs for optimal performance is up to 150ms. The system performance might degrade beyond this limit.

Resolution

To workaround this default timeout window for SaaS service can be re-configured  to see if this helps for completion of add data sources and for the next steps if this workaround doe snot helps.
