i deployed a nsx-t 2.4 manager on KVM with "medium" type, it worked just fine until i installed second manager(on another KVM host) and join it to the first one.

they all display the following messages on the web browser after i type in the admin account and password to login, as shown below:

i could not figure out why this error happen and it just can't be fixed after i restart services such as "ui-service" in the manager or even reboot the manager.

does anyone know why? the "manager.log" and "syslog" in the manager appliance did not show messages which is truly helpful.
