Hello all,
First post to this forum. Have to say first that I'm a Linux newbie, trying to learn just enough to get a NAS running on a HP G8 server for several weeks.
Latest troubles are with Nextcloud that I cannot access via the android client. But this is not what brings me to post today.
While I was trying to find a way to the above mentioned problem, I disabled the "ssl" option from "general system parameters" on the web interface.
As a consequence I'm not able anymore to log in OMV. Any call from the browser to http://'nasIP' switch automatically to https and displays an error message for incorrect web address.
I found via ssh connection that OMV stores in /etc/openmediavault/config.xml its settings and under <webadmin> section I switched back to 1 <enablessl> and <forcesslonly>. After reboot I still cannot log in.
So if you have any idea of what I should do to get back to the web interface I would be very grateful if you can spare me another reset from scratch.
Thanx for your help and sorry for the beginner's request. 
Laurent
