Firefox error

[Shion]

I am having this error when trying to go The Edge Singapore website

However, when on another device, I can access it without problems

What could be the issue ?

The root and/or intermediate certificates of the signers of www.theedgesingapore.com is not in the trust keys store of the Firefox browser. Firefox uses it's down trust keys store, not from the OS's

Go download the latest version of Firefox from their webpage, that should update your FF keys store to the latest version and resolve the problem.

Are you using any VPN or HTTP proxy or DNS proxy ?

Check in your Firefox Certificate Manager the following CA Root Certs are found

Also check your Connection Settings are as such

Use system proxy settings and untick for enable dns over https

Your system has proxy set right ?
If it has, then the rerouted traffic may be issuing you something else for the certificate.
Can't confirm if the act is malicious or intended, you should be cautious.

Google DNS 8.8.8.8 & 8.8.4.4

Google DNS 8.8.8.8 & 8.8.4.4

That's the DNS not proxy.
I changed to these 2 DNS resolvers, it didn't change the issued certificate chain.

Opps. Then I am not aware of any proxy.

Feel free to screen shot your system proxy settings for me to see, or you can set back to system proxy and see if the problem comes back again to know what is going on. There is certainly something fishy going on.

 

[Shion]

This you mean ?

Ok so after some testing, the result is that I must tick the "enable dns over https" otherwise I will not be able to access The Edge Singapore, regardless whether I choose no proxy, auto-detect proxy or use system proxy settings.

 

[davidktw]

This you mean ?

The Automatically detect settings may have applied something depending on what is installed on your system ?

If you set back to system settings in Firefox, does the problem comes back ?

Open up your command prompt and type netsh winhttp show proxy
What do you see get displayed ?

You have a DNS resolver within your own network ? Like Pihole, some kind of ad blocker or vpn that works by using DNS redirecting ?
The DNS over HTTPS helps to redirect your DNS resolution to Cloudflare directly over HTTPS when using FF browser.

Okay so what is left is your DNS resolving path.
