The virtual machine screen shows a 403 error

[dya]

■Environment
・ v. 8.1.1
・The number of HVM hosts is 2
・The data store is NFS

■Question
When I select a virtual machine under [Infrastructure] - [Compute], some virtual machines do not appear and return a 403 error.
The manager is fine. It seems that the separately provisioned virtual machine is returning a 403 error.

The URLs for each are listed below.
・manager
https://xxx.xxx.xxx.xxx/infrastructure/servers/3

・other
https://xxx.xxx.xxx.xxx/servers/show/4

By the way, to display “other,” follow the steps below.
https://xxx.xxx.xxx.xxx/infrastructure/servers/4

This seems like a bug, but has anyone else experienced the same issue? I'm using v8.1.1.
