Grafana upgrade to v11.2.0, v11.3.0 or v11.3.1, plugins page show "Not found" Error

Grafana upgrade to v11.2.0 (2a88694fd3), the plugins page shows a “Not Found” Error, and no plugins displayed, but there are a lot plugins installed.

I found some 404 Not Found logs:

level=info msg="Request Completed" method=GET path=/api/instance/provisioned-plugins status=404 remote_addr=xxx.xxx.xxx.xxx ...
level=info msg="Request Completed" method=GET path=/api/instance/plugins status=404 remote_addr=xxx.xxx.xxx.xxx ...

The Grafana is running in AWS EKS.
This error is also in v11.3.0 and v11.3.1

How to resolve this?
thanks!

Angular plugins?

No, I mean the Administration > Plugins page, thanks.

Did you try logout/login?

Sure, I logout/login a few times. but the problem still there.

backend service call backend service with APIs “/api/instance/provisioned-plugins” and “/api/instance/plugins”, but the two APIs do not exist, I thought this is why the plugins page shows nothing. right?

But I don’t know where and how to fix this.

config:

[plugins]
plugin_admin_external_manage_enabled = false
