I’ve been running into an oddity and i can not find the root cause.
Situation
I have installed OMV on my raspberry pi 4 4GB via:
wget -O - https://raw.githubusercontent.com/OpenMediaVault-Plugin-Developers/installScript/master/install | sudo bash
I also needed to use usrmerge before the installation:
sudo apt install usrmerge
After completion, while being connected via ssh, i can query the omv website and it works fine:
curl localhost
However whenever i try to access it via the browser, it does not. I have ran omv-firstaid as well just to be sure, but that does not change anything.
Network
My Network is connected via ethernet to a repeater (Fritzbox 4040), which in turn connects to the router via ethernet (Frityzbox 7490). Another repeater is also connected.
All are connected as a singular Mesh.
Question
I can connect via port 22 to my pi from anywhere in my house. It works fine and stable due to the mesh. However i can not connect to port 80 for OMV.
I’ve tried port forwarding on my network mesh, but that did not change anything.
I also tried for testing purposes a tunnel via ssh ssh -L 80:localhost:80 pi@raspberrypi.local but that resulted in a:
bind [::1]:80: Permission denied channel_setup_fwd_listener_tcpip: cannot listen to port: 80 Could not request local forwarding
Which makes me think it might be the network on the pi. However I am new to linux networking and therefor would like to ask for your ideas.

Some service is still grabbing your port 80, so the new job cannot start to listen there.
But this service is not really listening.
Maybe your first installation job is not 100% finished, but still ‘hanging around’ somehow?
Just a thought - I do not really know OMV.
