Important information, apart from the exact notification (screen-shot) are the exact Moodle version, PHP version, the theme you use, browser (Internet Explorer?). Also, the "security" settings of the quiz, like "JavaScript secutiry" or Safe Exam Browser being used.
Hi Dominique and Visvanath,
thanks for your rich input. I'm attaching some screenshots of the notifications I get. Meanwhile, I'm checking the aspects you comment with my IT team.

Just updating the notifications we get. This is what a student got while doing her test, this happened several times:
What sort of login system are you using?
If you are using some sort of single-sign-on system, these errors can seem very mysterious, because if the user loses their Moodle session, then the single-sign-on system will just generate a new one. So, it will look like they are still logged in, but you get errors like this because form submissions are rejected.
One way to diagnose this is to look in the web server logs, and see if you see too many redirects to login/index.php. Try filtering the logs by this student's IP address, to see if that makes it clear.

OK, they seem to be regular.
About the session time-outs: How long is your site's session time-out, how long is the exam?

Hi Visvanath,
session timeout is 2 hours. Most exams don't have any time limit, and they are not that long that trainees would need 2 hours to complete them. According to the feedback we got from students, the session finished quite quickly.

Hallo Beatriz
That was a walk-through of the common causes. Nothing positive there. You may want to follow the other sub-thread https://moodle.org/mod/forum/discuss.php?d=396960#p1601151, it looks promising.
