[Tangelo-users] No Response From Tangelo Server

[Grant Mc Auley]

Hello,

I am excited to try Tangelo, but am having trouble running it on an AWS ec2
instance of Ubuntu LTS 14.04.  I am trying to run the 'now.py' example
given in a blog post, but am getting a message in the Chrome debugger that
the connection is timing out.

#----------------------------------------------------------------------------------
It seems the server starts OK (although there is an error message):

#----------------------------------------------------------------------------------
This is url I use (the AWS ec2 instance public DNS name followed by 'now':

http://ec2-xx-xx-xx-xx.xx.compute.amazonaws.com/now


#----------------------------------------------------------------------------------
These are the permissions for now.py:

ubuntu at ip-172-31-44-22:/usr/local/share/tangelo/web$ ls -l
total 12
drwxr-xr-x 2 root root    4096 Feb 20 00:05 img
-rw-r--r-- 1 root tangelo 3789 Feb 20 00:05 index.html
-rw-r--r-- 1 root tangelo   67 Feb 20 20:45 now.py


Pardon me if I am missing something obvious, but any help would be
appreciated.
