Unable to reach Navigraph Server AGAIN

Hello! Sorry for the late reply.

Your logs indicate that your computer is spontaneously having a hard time reaching our servers. There are 6 (!!) instances of this error in your log:

But the majority of the requests are successful, which is great!

Our servers are hosted on AWS, the world’s leading cloud provider, and we have no reports of this being an issue for anyone else. Our server logs are showing a steady stream of incoming traffic from all over the world. The HTTP_CODE: 0 is to be considered an “undefined” error, and our servers would never send such a response. It is common for firewalls to be able to cause this, but in since the issue is intermittent in your case I find that a little hard to believe…

Any ISP, including a well-respected one, can have issues with this - they have to route the traffic from you to Ireland in this case. Bringing in other apps into the equation does not make any difference in this case, as they are very unlikely to be connecting to the same servers.

Let’s say that you are sending two packages to different locations. One arrives in time, and the other is returned to you due to the delivery company failing to find the location you provided. Would you then say that it should have arrived, because the other package had no issues?

Let’s then also say that the delivery failed because an intern misplaced a specific paper that connected your provided address to a real location. You send the package again, and this time they find the misplaced paper and can deliver the package.

Connection timeout issues can happen due to a myriad of different reasons, such as a faulty DNS server (which can be configured/changed on your PC, in your router, or at your ISP), a router firewall, a network driver update, router update, antivirus, etc.
My “real-world example” above describes the first possibility of a faulty DNS server.


All the above said, are you still having this issue? And if you do, have you tried a different connection and/or computer? Just to rule out any antivirus or local network-related issues.

We have had cases in the past where users have tried tethering their PC to their phone and that solves the issue, effectively narrowing down the scope of the issue to the router and/or network cable!

Kind Regards,
Malte
