I am getting the following Error message trying to connect from a client to a gateway via an application load balancer (ALB). I do NOT see this error when the client is connected directly to the gateway. Any insight on this is appreciated

“Error launching application:RuntimeException: The client version or cached module versions are not compatible with the gateway version. Please re-launchclient.”

Have you cleared Ignition’s client cache on the troublesome client?
