NW 11 setup throwing internal error after new deployment
You'll usually see this "internal-error” message if you log in to the UI before all of the background services have fully started up. While the login screen will be available nearly immediately upon appliance bootup, all the background services generally take a bit longer (maybe 5-10 minutes) to fully startup.
Still I am facing the same error, it has been hours since the server started.
do u have any idea, what services have to be checked on the server?
If you can SSH into the appliance and run "top,” you'll get an idea which processes are using the most resources. If any java processes are taking up large amounts of CPU, that is one of the better indicators that the UI is still in the process of starting up.
If none of those help, then from your SSH session you can try restarting the UI service (nginx) with the following command:
# systemctl stop nginx
# systemctl start nginx
You can check for proper startup of nginx with:
# systemctl status nginx
If you see any errors or warnings in that status printout, please let us know.
