I installed rocketchat on ubuntu server on virtualbox.
I couldn’t access the http://localhost:3000 page after installation.
The solution was to go to Machine>Settings>Network and changing the Attached to: from NAT to Bridged Adapter, and click ok to save configuration.
I restarted the server, and on the host machine I was able to access to configure rocketchat as admin.
Unfortunately I haven’t had success with port forwarding out of virtualbox. I have attempted to make a rule for Port Forwarding with the following configuration
Name: anything really
HostIP: blank which is the equivalent to 0.0.0.0. allowing any machine to connect.
Host Port: 3000
Guest IP: blank
Guest Port: I tried 80, 8080
no luck. If anyone figures this out that would be handy to run the vm with NAT network setting.
