SSL fault by Nextcloud setup on QNAP webserver


I had Nextcloud running on my QNAP webserver, it wasn’t running in dock or VM.
Due to an error I had to do a new setup, that gives me a error.

The whole QNAP is configured, all needed ports forwarded and also a QNAP SSL certificate is installed.

The web setup wizard shows the screen that all dependencies are found, what’s needed for a correct setup.

The next screen gives me the possibility to install Nextcloud in a subdirectory, when I press ‘Next’ the fault as shown on the screenshot is visible.

Is there anyone who knows how to work around this error?

Kind regards,


It’s all fixed, just by uploading te whole Nextcloud directory is it possible to run the setup by opening the website.
