I installed mindlessly OMV in my Raspberry yesterday and it broke my internet. It was my mistake and it was almost a clean install so I just reflashed the microSD and started over.
Now, following this guide, I installed OMV in Rasbian Lite. All was working perfectly, I accessed the webGUI and configured an SSD as storage. I had to go and took my RasPi to what's going to be it's permanent place.
I SSH'ed into the Raspberry and all was working fine. Then I look up for my new IP, (before it was 192.168.1.107) that's 192.168.0.81. When I put that in the browser, it doesn't reach anything. From the SSH I can ping other IPs and internet is working fine.
What I've tried:
- Using omv-firstaid to configure networking and to configure webGUI. It says webgui it's reachable at 192.168.0.81:80, but I try to paste it into the browser and it doesn't work.
- Changing the webgui port to 8080. Still doesn't work.
I checked:
pi@raspberrypi:~ $ sudo nginx
nginx: [emerg] bind() to [::]:8080 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:8080 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:8080 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:8080 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:8080 failed (98: Address already in use)
nginx: [emerg] still could not bind()(before it said the same but with port 80)
I saw a similar error in this forum and it solved it doing this:
sudo apt pruge nginx nginx-full openmediavault
sudo apt install nginx
sudo apt install openmediavaultAfter this, nothing really changed 
What else can I try? I really don't want to reflash the microSD because it isn't home and I'm using it from a VPN.
Other stuff that you might want to see:
