First let’s try to resolve by clicking Manage Apps, clicking the Red “X” next to Passkey Server and then reinstall it via the Umbrel App store. Please also try to reboot via System > Restart
If after ~5-10 minutes it is still unresponsive we can move on to manually uninstalling and reinstalling
Can you SSH into your Umbrel
Steps on how to SSH are available here: Official Umbrel Troubleshooting Guide and FAQ
Then run this command to manually uninstall:
sudo ~/umbrel/scripts/app uninstall passky-server
and then reinstall:
sudo ~/umbrel/scripts/app install passky-server
Can you share the entirety of the output of each these commands with me for review?
Let me know if there are any errors and happy to further troubleshoot.
