Getting untrusted site warning on every site I attempt to visit within Firefox while on 4G, but not WiFi

[jnelsoninjax]

Whenever I attempt to browse any website on my cell phone while connected to the 4G network yields me a message that this site is untrusted, regardless of what site it is (even Google triggers it) but when I am connected via WiFi, I can browse just fine. The only thing that I can think that could be causing the issue is Adguard, but it has never had any issues like this before. Has anyone else seen this type of error before?

Make sure the date on your device is set correctly.

Thanks for the response, I checked and the date is set correctly, and it is set to automatic from the carrier.

I get this problem in Firefox when I run Fiddler at work, which proxies traffic while it is running. So I’d check to see what might be proxying your traffic on your phone.

Yeah my guess is your being https is being proxied and you do not trust the CA that created the cert...  Check the details of the https cert and who/what created it, etc.

Adguard is your issue. I remember you having this issue on the computer browser too, adguard always seems to conflict with firefox after some time. Doesnt Adguard basically setup a VPN that routes your phone traffic through their servers and back to you, removing the ads? I can guarantee you that is your problem.

So does the issue go away when you disable AdGuard?
