Why Is My Flint 2 Router Presenting a Self-Signed Certificate?

Technical Support for Routers

Hi,

I recently set up a Flint 2 and noticed that my IDE (JetBrains Rider) prompts me to accept a self-signed certificate when checking for updates. My expectation was that HTTPS traffic would pass through without interception by default.

I haven’t configured any VPNs, DNS changes, or security filters yet, so I’m trying to understand why this is happening. Is the router performing some kind of traffic inspection, proxying, or DNS-based interception by default? If so, which setting controls this behaviour?

Thanks in advance for any insights!

Hello,

Under the default configuration (no ADG, DNS Auto, VPN disabled), no feature may intercept/check any HTTPS traffic.

To my expectation also is HTTPS will not be intercepted or redirected for the certificate.

  1. Make sure Flint 2 is completed the first initialization?
  2. Is there an exception to access HTTPS webpage in the browser?
  3. Does your computer have software like VPN/DNS enabled?

As far as I know the first initialization is complete, I don't have any special exceptions set up in the browser (although the above window appeared in my IDE) and no VPN is enabled. DNS is set to auto and provided by the Flint 2, which should be the default ISP for now as nothing else is configured.

The fact I'm being asked to trust certificates when accessing resources not related to that certificate from the router is very concerning to me, as you say nothing should be intercepted or redirected by default. If I don't find out what's going on then I can't trust this router and it's going back and I'm highly unlikely to return :frowning:

This happens sporadically if the first setup isn't done or the DNS intercepting is going crazy or the internet connection aborted at some point. Nothing to worry about, the router does not sniff traffic in any way.

Reboot the router and reboot your PC as well, to clear all DNS caches.
