This thing launched 50 years ago, it and it’s sister probe are farther from earth than anything else by multiple orders of magnitude, they’re literally outside the sun’s influence. We obviously aren’t getting them back so recovery must mean recovery to an operational state

Localhost would only work on the machine itself. I have Cosmos installed on my own computer, but I have no experience trying it in a virtual machine. That may be a question better suited for the Cosmos Discord server, I can get you an invite if you want it

Although if I remember right a separate backup agent is obsolete, the main Immich container can do backups now

Maybe that’s specific to my host software that manages docker, it’s called Cosmos Cloud. There is a pre-built Immich docker compose which has an option to add a backup agent.

First of all like the other commenter said make sure you have all the right Immich containers running, should be 4 to 5 depending on if you have a backup container.

In the webpage, not the app, go to server settings first, in the machine learning section check that you have facial recognition turned on and a model selected, read through in case you want to change anything else about it.
Then secondly go to job queue and try refreshing face detection and grouping.
