Unable to launch UI page


(Revs) #1

Hi All,

I have just completed a fresh installation and for some reason unable to launch the webapge. All the components are running fine, I am guessing it is an issue with nginx server failing to bind the IP.

Tried following this link, but not sure (update-system) mentioned at the end of the page.

What makes you think it’s an nginx binding problem? Are there some logs to indicate that? Or are you not seeing 443 in netstat -nltp?

My guess is that you have default RHEL/CentOS system firewall on, blocking inbound traffic.

Hi Lindsay,

The reason for considering binding problem, this server has mutliple NIC’s. I could not see any logs all files in /var/log/nginx/ are 0 bytes size. I can see all ports are listening

Also, I dont think its a firewall issue because iptables are disabled.

revs@xyz01:/opt/stackstorm# service iptables status
iptables: Firewall is not running.

Please guide me.

Regards.

If it was a binding problem, you would not see :443 in your output above.

this server has mutliple NIC’s.

That is probably at least partly related to your issues.

At this point it’s just a standard network troubleshooting process. Check that DNS resolves as you expect. Trace the packets between your client and the server. Identify any firewalls or misconfigured routing. Check that packets are received on the server. Check that the reverse path, from server to client is what you expect.

Talk to your sysadmins and network engineers if you aren’t familiar with this process
