Saw this: https://moodle.org/mod/forum/discuss.php?d=381429#p1537691. So, it a race against your colleague.
;-?

Whatever, as Ken explained in detail in the other thread, the network people at your school are the suspect number one. If they are stubborn, you (two) can organize a demonstration along the following lines:
- connect a laptop to the school network and let a student log in
- let him try to upload a file to an assignment which ends up in this network error
- disconnect the laptop from the school network and connect back through a private wireless hotspot, for example your mobile
- retry the assignment and show to them that this time it is successful.

if it is Moodle related, https://docs.moodle.org/35/en/Debugging will provide you with more information. If it is a network issue, the network administrators of your school must debug. Give them a dummy account and ask to upload a series of files, increasing in size.

Two observations:
- When you say "school network", are they school devices (not BYOD)? Possible the admins have installed a content filter or other other security features.

- Also came in today: "Student upload issues only on certain network" https://moodle.org/mod/forum/discuss.php?d=381429. Moodle 2.6 though. Coincidence?

Also keep an eye on this similar discussion: "error connecting to the server (depending on network connection)" https://moodle.org/mod/forum/discuss.php?d=381454.

Hi Faisal

I can not give an exact answer, since I have no idea of the "panel" you are working on. (My sole access tool is the Unix shell. That is a different subject.) In any case, saying "everything is fine" is risky!

If the site behaves all right for you, there are various checkups which you can do through the Moodle 'admin' interface. You can trust them (since you are trusting Moodle anyway ;) .

Every time a start a particular quiz the following error comes up:

Moodle 3.1.14+ (Build: 20180927)
Debian Jessie (8.11)
PHP 5.6.39-0+deb8u1

We haven't noticed this in any other quiz. The same quiz, the same set of questions, runs in a couple of other places without any trouble.

Amazingly found nothing in the forum under 'notenoughtshortanswerquestions'. Any clue?
