Base URL fail. http://xx.xx.xx:8080/secure/Dashboard.jspa is blank.

Hi everyone,

JIRA is not able to access itself through the configured Base URL

I have a fresh Jira 7.3.8 installation. No proxy, no apache. Fresh ubuntu 16 + fresh jira. All pages are accessible exept for /secure/Dashboard.jspa.
It hangs with a white page. I came through many sugegstions but all of them concern certificates and SSL, but I before I start configuering SSL I want simply access dashborads from :8080.
Maybe that's some ubuntu security settings?
Can you please help?
Thanks.

Errors:

ERROR [c.a.j.p.healthcheck.support.BaseUrlHealthCheck] An error occurred when performing the Base URL healthcheck:

It is what the error says - the server cannot reach itself over the base url you've given it.

This usually means you've got a misconfigured network, or a firewall on the local machine that blocks access from xx.xx.xx.xx to xx.xx.xx.xx on port 8080.

Check the firewalls and that /etc/hosts is correctly referring to localhost and your ip address if it's in there.

A simple test on the server is to try the command line:  telnet xx.xx.xx.xx 8080 will try to open a connection on that port and might give you a more useful error message.

Thanks Nic for the prompt reply. I'll get our nework team to sort it out. Meanwhile I was successul to "wget 127.0.0.1:8080" with response 200, but "wget my-host-ip: 8080" ends up in "failed: Connection timed out. Retrying." 
But jira is fully accessible from the DNS name, it is just long, ugly AWS name.

Sounds like my-host-ip is not set up correctly
