Node Red - The app is currently not available

[rantanplan]

Hello all,

I get the following error message when I start NodeRed.

Spoiler

The app is currently not available.

This is most likely due to one of the following reasons:

• The "Service Mode" is currently active. Please switch to "Operation Mode" and try again
• The app is currently being initialized. This may take a while, the page will refresh automatically.

If the problem persists, please contact the responsible app supplier. (HTTP Error 502)

The following was tested:
- Reboot

- The "Service Mode" is not active

- Waited 30 min

Does anyone have another tip?

Let me answer my own question.
- Switch to service mode
- Uninstall Node Red
- Switch to service mode
- switch to Manage App data (folder with gear on top next to user)
- Save to Archive (backup ZiP file)
- Open Zip File and delete the folder "Node-Red"
- Upload new zip file
- Load archive to br active
- Switch to service mode
- Reinstall Node Red
- Switch from Service Mode to Operation Mode.

This solved my problem.
