In troubleshooting manual see the sections:
- One Umbrel App do not start or it can’t be installed
- After a bad shutdown, the node is not syncing
- Some docker component fail to start
- Several docker services could not start - Failed to start containers
- I updated my Umbrel but it stuck in finish it
All of them are about how to reconfigure the node apps and settings (without losing any user data).
Try those.
