Tridion Asked on September 30, 2021
I am getting the below mentioned error when Publishing the "Publish Setting" in a load balanced environment
Related Error might be the cause as well
DXA 2.2 With SDL Tridion 9.1 is the Setup for this implementation
Notes Update section
I am able to access the discovery service from both the CM Servers involved in the setup.
Error from the Event Viewer is mentioned below

maybe first check DB configuration in CD Discovery Service, and test DB is accessible from CD with port number and user account. also verify the CD Discovery Service endpoint is accessible https://prod-discoverysvc.ccccc.com/discovery.svc. username/password is correct with topology setup. if not please provide test and maybe try other checks.

Looks like the issue is having communication issue from CMS to discovery service. Please register the keystore on CM for discovery service and enable keystore entry on cd_transport_conf.xml Example : Under sender type: DiscoveryService Keystore : <Ketstore Path=“jrepathlibsecuritycacerts” Secret=changeit”
Hope this helps .
