Hello together,
I'm not completely new to OMV and VirtualBox but I don't have any experience with OMV VirtualBox plugin.
I installed it from omvextras repo (stable) and it seems to work (didn't try to run a vm yet), but the "Advanced configuration" switch is nonfunctional.
I can enable it but the "preferences" section in phpvirtualbox stays as empty as before. (All the important options are missing.)
When I try to disable "Advanced configuration" again, I get the following message:
"Bad Gateway"
HTML
<html>
<head><title>502 Bad Gateway</title></head>
<body bgcolor="white">
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx</center>
</body>
</html>
Uninstallating and reinstalling the virtualbox plugin didn't solve the problem and I see this same behavior on two separate OMV 4 machines.
Please help me!
