Hello, thanks for you answer. We have many other forwarders, but they can directly contact the deployment server (they are on a separate network), and they work correctly. For this forwarder, we can't directly contact the deployment server, so we are forced to use the DNS and port 80. I tried changing the DNS name with the IP, but I have the same error: 02-24-2022 12:53:03.197 +0100 INFO DC:DeploymentClient - channel=tenantService/handshake Will retry sending handshake message to DS; err=not_connected Thanks
