Suddenly failing system check "Joomdle Web Services"

Help Please.

We have been successfully using Joomdle for many years without problem and suddenly without any changes occurring over the weekend that I am aware of (and I am the only System administrator) the Joomdle System Check is failing. The last entry "Joomdle Web Services" fails with the message "Received empty response from Moodle".

Our last successful Student login was 1 day ago, and I have spent the past 18 hours trying to figure out what is wrong.

I have checked all the settings in both Moodle & Joomla. Checked and Double checked website URL's and IP addresses. I have even uninstalled Joomdle in Moodle and set the system up again and still it fails the last check.

I rang our website host supplier to see if they had made any changes over the weekend and they assure me they have not changed any security settings.

I have tried everything I can think of.to resolve this and until I can, our Production Training site is not accessible by our Students.

We are using:

Moodle-Version 2.7+ (Build: 20140626)
Joomla version 2.5.22
Joomdle version 0.95

Main website www.qja.com.au
Moodle www.qja.com.au/moodle

If anyone is able to offer suggestions or ideas please help, I am at the end of my tether.

Thanks,
Keith Revell

Hello Keith,

It happened same with ur website. It has been running for almst 10 mnths withut issues and suddenly from last 3 days it has been showing "Joomdle web services error - Received empty response from Moodle".

We have:
Joomla - 2.5.22
Moodle - 2.2.11
Joomdle - 0.95

I have checked and rechecked the URLs in all places listed on docs, forums, etc. Security settings are OK, i tried to debug the system and set error reporting to max but could not catch the error.

What I have found is that auth.php in ../auth/joomdle folder of moodle is showing:

function process_config($config)
{
global $DB;

if (!isset($config->joomla_url)) {
$config->joomla_url = 'http://localhost/joomla';
}
set_config('joomla_url', $config->joomla_url);

is it good config to have http://localhost/joomla in there or to have URL of my website instead, i tried to change it but it doesn't affected error.

Hi guys, sorry to hear you are having troubles with your sites. The fact is, if nothing is changed you will get the same result. When something changes you may get a different result. Thus I can only assume that something has changed. Keith unfortunately, in your case you have already proceeded to uninstall and re-install which makes it impossible to see what has changed.

The next thing I would do is bring back my last known working environment from backup in a different folder and compare.

Same for Abhishek with the exception is regardless of whether that code is correct or not, if it has been working for 10 months now, it is not likely to be the problem. Again, something must have changed in your environment to cause a different result.

While checking server error logs I found this:

[Sun Jul 27 14:13:23 2014] [11975338] [fcgid:warn] (104)Connection reset by peer: [client 119.63.193.195:61983] mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

seems like GoDaddy has recently switched on mod_security, I feel somehw this is cause of Joomdle Web services Error which came out of the blue just like this!

We are with GoDaddy as well. I rang their technical support and they assured me the ModSecurity had not been changed??. Is there any way of checking this separately?

Assuming this is the issue, it is the reason we don't use Godaddy for hosting. Previously the front line thought their servers supported XMLRPC but after many rounds of fighting their engineers confirmed XMLRPC was not supported. Of course this has subsequently be changed as I understand they support XMLRPC.

Have you tried looking at phpinfo to see if mod_security is enabled?

As for checking ...
www.google.com.sg/webhp?sourceid=chrome-...20for%20mod_security

GoDaddy have finally responded to my fault report after a week and a half and advised that they had to apply some Host Server Patches to fix our problem. Very strange that it "suddenly" failed and they denied changing anything!!

I think we will be looking for another website host soon. Anyway, services have resumed as normal and everything is again working OK. Thanks for your help.

Keith

As of 08.August.2014 suddenly my Joomdle Web services have also automatically resumed back to normal, and error regarding mod_fcgid disappeared from Godaddy error logs, meanwhile in panick I migrated whole of my site to another server, VPS is the best option I guess to run joomla-moodle-joomdle successfully.
