Troubleshooting 'Morpheus is Loading' after VME Install

[GWUK]

Hello,  after getting a VME instance installed with the simplest networtk config possible (Single 1G LAN),  I've got yhe VM Manager installed,  and the VM it creates is pingable and contactable via SSH.

However, all I get via the web interface is 

After I while this times out and I just get Webserver  HTTP Status 400- Bad requests on redirects to /setup/index URL's.

Morpheus-ctl status on the guest shows -  

avon@v-af-vmetst:/$ sudo morpheus-ctl status
run: check-server: (pid 2134) 2424s; run: log: (pid 864) 2473s
run: guacd: (pid 886) 2473s; run: log: (pid 860) 2473s
run: morpheus-ui: (pid 1987) 2449s; run: log: (pid 865) 2473s
run: mysql: (pid 890) 2473s; run: log: (pid 862) 2473s
run: nginx: (pid 892) 2473s; run: log: (pid 855) 2473s
run: opensearch: (pid 888) 2473s; run: log: (pid 861) 2473s
run: rabbitmq: (pid 889) 2473s; run: log: (pid 863) 2473s

This is using the latest .12 release, and have tried with or without Ubuntu updates on the host. Running on HP DL380G9 bare metal.

Any advice how I can further troubleshoot this please ?

I have come to find out that the time for loading will very much depend on the machine. I have seen it take 30 minutes up to 90 minutes for the setup to be complete.

Running morpheus-ctrl tail whilst mopheus-ui was restarted showed some interesting infomation which is probably the root cause.

For legacy reasons we have an underscore  ( _ ) in our domain name, which generates a java exception 

java.lang.IllegalArgumentException: The character [_] is never valid in a domain name.

I'll try the setup again using another dns domain without an underscore.

It might be worth considering an edit check on the input fields in hpe-vm if this is never going to work.

Thanks.
