Received empty response from Moodle

I think you should put the custom php.ini file in all the needed locations.

This is a list another user posted some time ago. Not sure if all are needed, or if there is any missing.

/joomla
/joomla/administrator
/joomla/moodle
/joomla/moodle/admin
/joomla/moodle/login
/joomla/moodle/auth/joomdle

I've just noticed that www.environmental-academy.com/test.php no longer works now. It now states:

Moved Permanently

The document has moved here.

Any idea what may have caused that? I have contacted my server's support team and they say they have not changed anything since it worked last time.

I have also just tried adding the php.ini file to suggested directories without success.

I really want to get Joomdle working for my company's LMS. We currently spend around 3000 USD a year on a bespoke LMS and other plugins which I am hoping to replace. I would be more than happy to make a donation if we can get this working.

I understand that this may be a difficult dead-end though if there are many variables which could cause this in my server setup.

Do you have any other ideas/tests?

I don't know why you get that, but it's sure because some server configuration, as I created the test.php script on my server and it is working fine, so the problem only happens when the server connects to itself.

I have never seene this behaviour, so I am not sure where to look now... I would contact support again and explain the simple problem: test.php works from outside, but not from inside.

Thanks Antonio, I agree it must be some kind of weird server configuration. Unfortunately the support team at our server don't seem to understand the issue and aren't able to help.

I'll have a few more attempts at finding out what the issue is and post solution here if I have any success.

We've managed to get the test.php file to work by changing the url to the absolute path (i.e. putting /index.php on the end). I'm not sure why this suddenly had to be done since it worked without this before.

www.environmental-academy.com/test.php now retrieves the moodle installation correctly.

What does that suggest? Does this show that the server can connect to itself? Is there anything else I can check for what is causing "Received empty response from Moodle"? I have checked all the settings over and over again, so I am convinced it is something to do with the server settings, I just need to know what I should ask for them to check?

I have tried placing the custom php.ini file in the directories again and it still has no effect.

Make sure you have file_get_contents selected as connection method in moodle side.
Aside from that, I can think of anything else to check. At this point I would just debug the code.
