QNAP [ FireFox Sync Server ] [ 1.5 ] Browser synchronization

Hi,

I installed the FireFoxSync qpkg from the provided link but I get an „Internal Server Error“ as soon as I edit the syncserver.ini.

Without editing the syncserver.ini I get:

Code:
{"status": "error", "errors": ["The public_url setting doesn't match the application url.\nThis will almost certainly cause authentication failures!\n    public_url setting is: http://localhost:5000\n    application url is:    http://192.168.215.26:5000\nYou can disable this check by setting the force_wsgi_environ\noption in your config file, but do so at your own risk."]}

Then I edited the host in [server:main] and the public_url in the [syncserver] section of the syncserver.ini. Both values are set to my internal NAS-IP-address because I just want to use the sync locally.
After restarting the service I get the „Internal Server Error“ when I try accessing „http://192.168.215.26:5000“ with FF for testing.

Even configuring the ini-file back to the original settings ends in the same error. Uninstalling the qpkg and reinstalling also did not help.

As expected the modification of „identity.sync.tokenserver.uri“ does not work.

Any suggestion?

Best regards,
Alexander

Edit: Stopping and restarting the FireFoxSync in the AppCenter directly after installation also results in an "Internal Server Error"...
