QNAP After the update, there is no access to OwncloudX

I updated phpMyAdmin to
I updated MariaDB 10 to
OwncloudX in the AppCenter panel is running, but when I click “open,” I can’t access it from the browser; I receive the message “This site can’t be reached.”

This is a server in a company; at home, I set up a server on a computer with Debian, where I have a private OwnCloud, and I don’t have such a problem there.
