Bitcoin node stopped syncing

A few days ago my node stopped syncing new blocks. When I pull up the app it is an empty template. I am running my umbrel on a raspi through ethernet.

Hello, my node has also been having sync problems since a few days. Closing from the command line gives me this error: The Compose file is invalid because:
Service app_proxy has neither an image nor a build context specified. At least one must be provided.
