Hi Jeff<br>
<br>
My first reaction would be to disable SELinux and Iptables
completely (setenforce 0 && iptables -F). Then try again and
let us know :)<br>
<br>
Good luck<br>

Dashboard is installed on my controller node. When I first
installed dashboard and tested, I was able to login as "jeff"

Mozilla Firefox and Google Chrome. I looked through
/var/log/error_log and found that the problem was a
ConnectionError in
/usr/lib/python2.6/site-packages/requests/adapters.py line

different source ports to port 80. I haven't a clue why,
it makes the second third, and fourth connections before
it ACKs the first connection. Then it does a GET

Then the second session is closed down. I don't see
where the third and fourth connections shut down. My
hypothesis is that Chrome is opening sessions at startup
to optimize performance, and that this is confusing the
server. HTTP is supposed to stateless, but HTTP runs on
top of TCP and TCP is stateful, so isn't clear to me if
browser or the server is violating RFC 2616 (see the
abstract).</div>

<div class="gmail_default" style="font-family:'times new

/dashboard and gets a 200 response. Then the server
closes the connection. Next, firefox does a request for
/static/dashboard/img/logo-splash.png. The server
responds with a 304 Not Modified. That makes sense - I've
run this test a lot and the .png file is in the browser's
cache. Firefox does a POST /dashboard./auth/login and
this time, it specifies connection keep-alive. The server
replies with a 200 OK (should be a 401 unauthorized code,
but that's a digression) that the login failed.</div>
