moodle 3.1.3+ (Build: 20161118) / php version is currently 5.6 / OS CentOS release 6.9 (Final) / Apache
Server version: Apache/2.4.27 (Unix)
I have set up an externally hosted course for my students.
When a number of students do a quiz ( >10) they get the following message :
""The following error was encountered while trying to retrieve the URL: http://mrshorecomputing.co.uk/mod/quiz/processattempt.php
Read Error
The system returned: (104) Connection reset by peer
An error condition occurred while reading data from the network. Please retry your request.
Your cache administrator is webmaster."
Is this error caused by ht hosting side ( the company say the activity is not large) , the code or the schools / my room set up?
How can I approach fixing it?
Most grateful for any help!
