I'm sorry you're having problems with the VM. Let's try to troubleshoot it!
When you changed the VM's network to bridged mode, did you restart the VM?
I'd need you to log into the VM. You should see a message like "If the above URL does not work, try connecting to these IP addresses instead". Could you copy here the list of IP addresses you get?
When you say you run aggregate-config --fqdn 192.168.5.2 --http-port 1234, the value for the --fqdn argument should be one of the IPs from above or a DNS name that resolves to one of those IPs. Could you check that, please?
• I shut down the VM for me to change the network to bridged mode
• I was able to reach ODK Aggregate using the "If the above URL does not work, try connecting to these IP addresses instead" but it then redirected to the IP Address I had set using the aggregate-config script which of course then failed.
• I did use an IP address from the block of inside addresses. The other address it suggested I use as an alternative was obviously a DHCP assigned address.
I was forced to do my own VM install from scratch, which is working.
Would you be willing to help us troubleshoot the issue with the VM? I know it doesn't affect you now, but it might affect someone else in the future and I'd like to prevent that future person from suffering
