site2site issue between nifi intranet and nifi gcp

e-sociaux Tue, 25 Mar 2025 00:17:05 -0700

Hello all,

Somebody has already done a site2site configuration between nifi intranet and nifi gcp ?

From nifi intranet we use a proxy to try to communicate with nifi gcp.

In the gcp console, we have created a VM with loadbalancer for public DNS entry, and setup the port we need to use.

There are some warning and errors.

The handshake seems ok like there is blue circle "remote process group" but there is no data sending from nifi gcp to nifi intranet

- Somebody already configure the VM gcp with loadbalancer in GCP and could help me about the network configuration ?

- Are we need to some specific configuration from nifi.properties side ?

In attachment, the logs we got for more details

Thanks for you help

Minh
