How to Resolve Failed to Connect SR Node Warnings

This tech note is for AVEVA System Platform 2023R2 SP1 and higher.   There is potentially a problem when a platform by itself (with no cascade) takes a long time to deploy.  The platform takes as much as 15 minutes to deploy.  Messages may be found in the Log Viewer such as the following. 

One thing to check is the ArchestrA Services.  Run the ArchestrA Services utility to check for issues.  This may be run from C:\Program Files (x86)\Common Files\ArchestrA\Services\aaServiceConfiguration.exe

Type in the name of Repository Node and Solution Name.  Leave the default as localhost if running from the GR node.  Click on the Connect button.

Select the Nodes tab at the bottom left.  The icons for MxDataProvider and Authentication indicate the services are not deployed to the platform.

The MxDataProvider and Authentication services will display icons indicating they are not deployed.  

Check and enable TCP Port 808 to and from the remote platform and the GR node.  

The Microsoft PortQryUI may be used to check the port to verify the port has been opened on the firewall.  

Right-click on each of the platforms to select Deploy from the dialog.

The services will deploy now enabling a much faster platform deployment.
