NSX Manager UI is not loading even when NSX Clustering is up

NSX Manager is slow to load and tasks fail with message server is overloaded or too many requests.

Solution

1. SSH to one of the NSX Manager that is a member of the cluster.
2. Run admin CLI get cluster status.
3. If cluster status is stable, run get services or get service <service-name> and verify that the following services are running: http, manager, search, ui-service.
4. To restart or start the stopped service, run restart | start service <service-name>.
