Hey guys,
I've installed openmediavault on my ubuntu server. The server is a virtual server which runs with an Ubuntu 14.04, it is hosted by strato. On the server an apache2 with a website and mysql database is running. now i installed omv, changed the default port of nginx to 81, I can reach the omv login page, but with the default user and the default password nothing happens. it says there was an "communication error". same happens when i change the password. I've rebootet the server, i've reinstalled omv. What can I do now?
