Hi…,

Welcome.

Please uninstall Navigraph Hub, download, install and run latest Navigraph Hub

Any improvement?

Cheers

Hi Ricardo,

Navigraph Hub talks to our servers using SSL, which means it verifies that it is our servers by asking for an SSL certificate to prove that it’s us it is speaking to. Think of it like a digital ID card for websites. This certificate is issued by a trusted 3rd party organization called a Certificate Authority (CA).

You are seeing this error because Navigraph Hub is encountering a certificate that hasn’t been verified by a recognized authority when trying to connect to our servers and, therefore, cannot proceed as the connection cannot be trusted.

This can happen if you use Navigraph Hub on a computer with an SSL Proxy or other network analysis tools installed, or on a corporate or public network where internal traffic is being analyzed before reaching its intended target. Perhaps the problem appeared after installing some other software, changing ISP or router?

Kind regards,

Markus

Hi, M4rkus, the problem appeared from one moment to another, I didn’ change anything but now I can´t update neither the FS2020 nor the FenixSIM databases. What can I do?

You need to make sure that whatever is adding a self-signed certificate to your chain stops doing that. Do you use any antivirus? See this for more details:

Proxies

Issue
Your internet connection is behind a proxy or is being intercepted. There are multiple reasons why this might be the case, here are a few examples:

• You are using a work computer that has a proxy set up by default
• You are using a proxy for personal/security reasons
• Your anti-virus is intercepting all traffic to scan for malware
• Your anti-virus/network security software has installed a self-signed certificate to encrypt insecure connections
• You have tried to reverse-engineer our or someone else’s applications using reverse-proxy tools like Wireshark, Charles, and the BURP suite and then forgot to turn it off.
• You have been infected with malware that is now actively deploying a MITM (Man-in-the-middle) attack towards you.

Proposed solutions

• Disable any proxies
• Investigate if turning off any anti-virus solves the issue
• Disable any active reverse proxies
• Investigate if your antivirus has any features related to scanning/intercepting network traffic. If it does, try to find related settings and turn them off temporarily to see if that resolves the issue.
• Run virus scans for the whole system. Also, run a rootkit scanner such as this one .

Hi, how are you? Happy new year! Yes, finally I could resolve the issue downloading the Navigraph Hub in a different computer, opening the app and signing in that computer (that generated another kind of error) and then opening the app in my computer and signing in again.

Happy new year!

That sounds very odd, but I am happy that it works for you! Thank you for the update!
