Hi Everybody;

As some of you know, we get back into development with CubicWeb.
Indeed we have two CW Instances running on a Amazon EC2 instance. One is
our beloved kanban, and the other is a solution we are "hopefully"
delivering next month ( a small cms, for a Metrology Lab).
We experience some internet connection issues while visiting our clients
for a demo, and then, the instance stopped, sending the message at the end
of this mail ( Clients weren't looking, fortunately ). This happened twice
today.

*Strangers Things: *

. Our CubicWeb instance stopped (crashed sound more pro/dramatic).

. The web adresse send a :

*La página crealibre.org <http://crealibre.org> no está funcionando  *
*crealibre.org <http://crealibre.org> no envió ningún dato. *
ERR_EMPTY_RESPONSE

- EC2 instance working, along with our kanban in another port of the same
instance.


NOTE: Unfortunately, we still are on CubicWeb 3.18.8.


Any ideas and help related to this issue will be more than welcome.
