Wagn "Problem Loading Page" error

[chris]

Bug report from Tom:

I've encountered a problem when trying to set up new accounts: I get a 'Problem Loading Page' error when it tries to load ​http://localhost:3000/wagn/Invite_Success. This seems to be explained at ​http://wagn.org/Special_Urls_and_Ports - which I am hoping falls under your area of responsibility as I'm not sure how to do it myself,! But let me know if not...

[chris]

There was no config/wagn.rb file so I have created one with this in it:

System.base_url = http://patterns.transitionresearchnetwork.org:80

And restarted the server as per wiki:TransitionResearchWagn

[chris]

However creating a wagn.rb file didn't solve the problem, Tom has raised a ticket about this here: ​http://wagn.org/Site_admin_functions_redirecting_to_localhost_rather_than_domain_name

[chris]

Ethan as replied to the ticket, ​http://wagn.org/Site_admin_functions_redirecting_to_localhost_rather_than_domain_name and updated the docs, ​http://wagn.org/Special_Urls_and_Ports

So I have added this to config/wagn.yml:

host: patterns.transitionresearchnetwork.org
protocol: https

And restarted the WEBrick server.

I have also deleted the config/wagn.rb file.

Ethan asked:

I'm not sure why this is not happening correctly for you or where the "localhost" issue is coming from, unless you already have something like "host: localhost:3000" in wagn.yml?

This is because we have a Ngnix reverse proxy running in front of WEBrick see ticket:561 for more detail, we have also upgraded to Debian Wheezy since then.

Ethan also said:

I would also suggest you look closely at ​wagn in production, which offers some key hints for making wagn run more speedily. If, for example, you are not using memcache, I would *strongly* recommend it!!

I'd be happy to go down this road, installing Phusion Passenger and memcache and using the mysql2 adapter in database.yml, but it would probably take a few hours to set up, we opted for the WEBrick server with a reverse Nginx proxy to start with because it was very quick and easy to set up.

Report from Tom:

This has changed the redirect address, but to one with extra text in that
doesn't work!
​https://patterns.transitionresearchnetwork.org/httpspatterns.transitionresearchnetwork.org/Invite_Success

I've updated the support ticket at
​http://wagn.org/Site_admin_functions_redirecting_to_localhost_rather_than_domain_name

I have commented out the protocol to see if this helps, so we have this in wagn.yml:

host: patterns.transitionresearchnetwork.org
#protocol: https

Ideally we wouldn't specify the protocol and links would either be in this form:

/recent

Or like this so they work with HTTP and HTTPS:

//patterns.transitionresearchnetwork.org/recent

We are using a STS header (see ​https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security ) and redirecting logins to use HTTPS to ensure security at the Nginx level:

        # Redirect logins to HTTPS
        # http://wiki.nginx.org/NginxHttpCoreModule#location
        location ^~ /account {
                rewrite  ^(.*)$ https://$server_name$1 permanent;
        }

This is resolved, closing the ticket.
