gateway issue - cluster setup

Hi merkol​,
The DMTS_GatewayIsDisabled message is expected because the old gateway was intentionally disabled; the actionable error is the Mashup query execution timeout on the new gateway server. Since Server 2 is in a different data center, run the gateway Network Ports Test and verify the required firewall and proxy connectivity. Also verify the proxy configuration, including Microsoft.Mashup.Container.NetFX45.exe.config, as Microsoft documents this for cloud data-source queries through the gateway. Finally, ensure both cluster members are running the same gateway version, as Microsoft recommends keeping cluster member versions in sync.
