Error while adding or updating a new subnet under VPC Private Service Connection

Problem

While creating or removing a private service connection, the below error was observed:

Cannot modify allocated ranges in CreateConnection. Please use UpdateConnection.

Environment

• VPC Networking
• Private Service Connection

Solution

To recreate the connection (once deleted), you have to use the gcloud command as mentioned below.

gcloud services vpc-peerings update --service=servicenetworking.googleapis.com --ranges=[Allocated_Range_Name] --network=[netowrk_name] --project=[project_id] --force

Cause

Creating a private connection is a one-time procedure. Generally this error generates, when you delete the previously created connection and allocated IP range and try recreating the new connection with previous allocated ranges.
