Hub error - self signed certificate in certificate chain

Navigraph Hub
1

Hi all,

I am currently having this issue, I saw the topic that says to sign in from another computer but unfortunelty it didn’t work.

I have the latest version.

I tried re-installation.

I restart every possible component that might be related to it.

I will be happy for help.

Thanks!

Hi @yav123

The issue you’re experiencing happens when another program on your computer is intercepting the secure connection between Hub and our servers. Here’s what’s going on:

When Hub connects to our servers, it uses SSL/TLS encryption to keep your data safe. This creates a “chain of trust” - essentially Hub verifies it’s talking to the real servers by checking their security certificates, like checking someone’s ID at the door.

However, certain programs on your computer can insert themselves into this connection to inspect the traffic. Common culprits include:

  • Antivirus software with “HTTPS scanning” or “web protection” features

  • Corporate security tools or firewalls

  • Packet sniffers or network monitoring tools

  • VPN clients with traffic inspection

  • Parental control software

When these programs “man-in-the-middle” the connection, they break the chain of trust. Hub sees an unexpected certificate (from your security software instead of our servers) and rightfully refuses to connect - this is actually Hub’s security working as intended to protect you from potential attacks.

How to fix it:

  1. Identify the interfering program - Check what security software is running, especially anything with web/HTTPS scanning features

  2. Add Hub to the whitelist - Most antivirus and security programs let you exclude specific applications from traffic inspection. Look for settings like:

    • “SSL/TLS exclusions”

    • “HTTPS scanning exceptions”

    • “Trusted applications”

    • “Web protection exclusions”

  3. Temporarily disable HTTPS scanning - As a test, try temporarily disabling HTTPS/SSL scanning in your security software. If Hub connects successfully, you’ve found the culprit and can then add a permanent exclusion

Unfortunately, we can’t bypass this security check on our end - it’s a fundamental part of how SSL protects your connection. The solution requires configuring the software on your computer to allow Hub to pass through without interference.

Kind regards,

Markus
