Hi again,
OK yes, your IT support may be able to say if they changed any server settings that might have affected the Nanogong connection. If your webhost is part of your organisation then they might be able to help you track this down, especially if it was working at some stage recently.
I recommend you look at the idea of setting up a local version of Moodle, even though you are not an "informatician" - I like that word!
- for a few reasons:
- it's probably easier than you think and people will gladly help if you ask,
- you will be able to safely explore extensions and plugins as well as isolating problems such as this Nanogong one,
- you will be able to develop course material offline and upload them (very useful for quiz development),
- it can help you store offline backups of your courses and material, and
- you will become more informed generally about Moodle and similar web applications so you can make better decisions about your e-learning strategy and sort throught the advice you may receive from others - particularly for webhosting.
Once you get a local installation going you will find that it is very similar to working online, but you will be surprised at how much more is possible. It's a good investment in effort as a Moodle-based teacher.
There are several ways to get started with a local installation. The Moodle Documentaion provides easy installation versions for Mac here:

and Windows here:

If you decide to do this and you need help just ask. Some of the documentation makes it look harder than it actually is.
Cheers,
Mike
