If you encounter issues with Syncthing, such as changing settings or forgetting your password causing the app to no longer load, you may need to reinstall it. However, sometimes the app configuration is not removed during reinstallation, leading to the same issue persisting. Here are a few ways to fix this:

1. **Via rutorrent File Manager:**

   - Go to the file manager in rutorrent.

   - Navigate to the ".config" folder or the local folder at the bottom.

   - Right-click to delete the "Syncthing" folder.

   - Reinstall the app.

2. **Via FTP:**

   - Log in to your FTP and navigate to the ".config" folder or local folder

   - Delete the "Syncthing" folder.

   - Reinstall the app.

3. **Via SSH:**

   - Log in via SSH.

   - Navigate to the ".config" folder opr the local folder

   - Execute the command: `rm -r syncthing`.

   - Reinstall the app.

In all cases, the solution involves deleting the "Syncthing" folder from the ".config" or local directory and then reinstalling the app. This will reset the app to its default settings and resolve any configuration-related issues.
