I have an owncloud server hosted on a virtual machine. I've been accessing it fine via My PC on the same network until randomly today this isn't working.
I just get the error "This site cannot be reached ERR_CONNECTION_TIMED_OUT"
I don't really know where to start looking, as i haven't changed any settings/files.
I can still access the URL from the web browser on the virtual server in which it is hosted, just not through any PC on the network.
Maybe some update broke network settings.
Check connectivity with a ping.
If ping fails and you are sure that any firewall isn't blocking ping's protocol (ICMP), then check your virtual network configuration.
Please dont use localhost as destination address. Use vm ip instead.
