Hi all,

I have a pretty weird bug that is troubling me, if anyone has any clues, 
there will be more than welcome!

We have a local arangoDB and a live arangoDB setup with the same 
configuration. I am continuously receiving a 408 timeout error from my 
application but only in the live server and not the local (development) 
one. I isolated the HTTP request that was returning the error, the request 
seems to run an aql query in the arango database. When I execute the 
specific query from the arango interface it returns results every time 
without an error both in my local and live database. On the contrary, when 
I send the HTTP request from POSTMAN service I sometimes get the following 
error : "Client Exception 408 Got a timeout while waiting for the server's 
response", while other times it returns the results. This happens ONLY in 
the live setup while in the local one it returns the results every time I 
send the request.

After sending several requests I noticed that every time that I got an 
error, the response time was more than 3 sec, while when I saw results the 
response time was always less than 3 sec, so I assume that is to blame. I 
checked the apache configuration that has the default timeout time at 30 
seconds and then moved on to arango. After some digging, the only thing 
that I could find related to 3 sec was the following:  CLIENT options: 
--server.connect-timeout <double> connect timeout in seconds (default: 3)  
from https://docs.arangodb.com/3.1/Manual/GettingStarted/Arangosh.html. Let 
me point out again that this happens only to the live server while sending 
the request in the local server may take up to 14 seconds but always 
returns the data.

The troubling thing is that I have the same setup and same configuration of 
arango in both machines, yet the timeout seems to be a problem only in the 
live one, does anyone have any idea?
Moreover, I could not find any documentation as to how to change that time 
and since I should have to do tests on a live server I want to be sure of 
what I am changing.

Thank you all for your time.

All the best,
Afiontzi Eleni
