We are trying to setup 2 VPC peering connections to mongodb atlas Each from a different GCP project. We are getting the following error when trying to setup the VPC network peering in GCP when trying to setup the 2nd one (the 1st connection works).

Operation type [addPeering] failed with message "An IP range in the local network (XX.XXX.0.0/X0) allocated by resource (projects/XXXXX/regions/XXXX/subnetworks/default) overlaps with an IP range (XX.XXX.0.0/X0) in an active peer of the peer network."

Any assistance would be appreciated
