What could be the reason for above errors and what steps we can perform to resolve this issue.
Kind of thought those error’s looked familiar. Because of the new permission for Graylog 4 we had to redo our Authentication Service’s “Active Dircetory” after upgrade from GL 3.3.x to GL 4.0. First I had to log into Graylog with the default credentials, then reset the Active Authentication Service. Only took a couple minutes. If its only for one dashboard I would look into all the service logs.
Sorry I’m not familiar with docker, but I know other people in here that is. If you could show you configurations they would be able to help you better. Basically what does your environment look like.
