[LON-CAPA-admin] View warnings from resource that doesn't publish

The "443 warnings" suggests that this is related to port 443 (i.e., https). 

My guess is that response coming back from an LWP request to render "Lee Test Problem 3.problem" (with POSTed args: grade_target'=>'web', 'return_only_error_and_warning_counts' => 1),  when you attempt to publish, is the string:

Can't connect to hostname.lon-capa.illinois.edu:443

which LON-CAPA then splits on the colon 
into an "errorcount" of:  "Can't connect to hostname.lon-capa.illinois.edu" (which is listed as 0 errors) 
and a "warningcount" of 443 (which is listed as: 443 warnings).

For the URL of your standalone server/VM, whatsmychaincert.com reports that your SSL chain is misconfigured, whereas for your production library server whatsmychaincert.com reports that the SSL chain is correct.

I would compare the Apache SSL config (specifically the certificate chain) on this server/VM with the one on your production library server (for which the script below does not report an error).

I tested requests for the URL: ht  tp s : // hostname.lon-capa.illinois.edu/adm/about.html
(removing the spaces from ht  tp s : //  which I put there to stop Proofpoint modifying the URL in this post to the list, and replacing hostname with the actual hostname of your server/VM).

(a) from a web browser, and 
(b) from a script on CentOS 7 which uses LWP.

The browser fetched the page OK, but the script returned:
Can't connect to hostname.lon-capa.illinois.edu:443

Here is the script:


use strict;
use LWP::UserAgent();

my $ua=new LWP::UserAgent;
my $request=new HTTP::Request('GET',"https://hostname.lon-capa.illinois.edu/adm/about.html");
my $response=$ua->request($request);
print $response->content;

Subject: [LON-CAPA-admin] View warnings from resource that doesn't publish

We have an isolated library server that I am attempting to publish resources on.  Creating the course and authoring space appears to have gone well, but when I attempt to publish a resource I am getting a bunch of warnings, no errors and a failure to publish.  A similar thing occurs when I attempt to clean the problem.

Is there a good way to view those warnings?  They aren’t visible in the normal interface and I’m hoping they might shed some light on what I’ve configured wrong.
