Windows 10: "Your connection is not private"

I keep getting this error with almost every website I go to, Google, Reddit, Facebook, etc.

"Your connection is not private
Attackers might be trying to steal your information from Google (for example, passwords, messages, or credit cards).
NET::ERR_CERT_COMMON_NAME_INVALID"



I get a similar error with Firefox, Internet Exploder, and Edge. This has been going on ever since the other night when my roommate decided there was something wrong with the internet (was working fine for everyone else) and did something to it in an attempt to "fix it." She's not home right now, and the person who has the internet in their name isn't, either, so I can't contact AT&T to fix it. How can I fix this myself?

:)

Upon N97 Mini map data could be stored upon either mass memory or memory card with choice available within Nokia Maps application > Settings. Don't want you removing map data unnecessarily but you may possibly need to delete both E:\cities and F:\cities
+ .qf file and re-start Nokia Maps application to re-define necessary folder structure; it may help to set Nokia Maps "Online" and download a few kb's of map data via WLAN access point by zooming in to your current location and start again downloading maps
to chosen destination.

Almost certainly as not enough free phone memory to store maps.

 

Is it only your computer having the problem?

 

Nope. My phone and both my tablets, too.

 

Sounds like they did something on the router that is filtering secure traffic, which typically involves installing a self-signed certificate to decode the traffic, analyze it, then re-encode it.

Regardless, unless you have access to the router password, probably nothing you can do.

 

Nah. That's too clever. They probably just did something really stupid like setting WiFi security to 'None'.

 

Bree all OS's are doing that now when it comes to WEP or no security. I have seen it on WPA/WPA2 Mixed for the service that Holiday Inn Suites use.

 

Yeah , sounds like the routers encryption has been turned off , check the properties of the wifi connection and see what it says.

 

Sometimes it is actually the device that is the culprit. With the changes to iOS 10, you get a whole new type of message when you are on a unsecured network, even if it is using WPA/WPA2.

 

^ This.

Your connection is being Man-In-The-Middled by something. Therefore your browsers are warning you that the Common Name on the TLS certificates are different to the URL's displayed in the address bar of your browser. I.E. The Common Name on the TLS Certificate for www[.]google.com isn't actually showing www[.]google.com as it should be.

You need to speak to the person who owns the router/internet connection (the bill payer) as you're roommate shouldn't be screwing with the router in this way. Assume everything you've done during the time when you've been receiving the warnings has been read by someone else in plain text, including all usernames and passwords. Therefore if you were able to bypass the browser warnings, once the problem has been rectified and you're no longer receiving the warnings, you're going to need to change all passwords that have been used during that time.

If you go to www[.]google.com in Internet Explorer, then click on the padlock in the address bar > View Certificates (you can't do this in Edge), the below pic is what the Google TLS Certificate should look like. You'll probably find something else showing instead of www[.]google.com, hence the warnings. But that's of course if the browser will even let you, because poor browser design quite often means it's not possible to see the certificate that's causing the errors. I very much doubt there will be an actual padlock on your computer due the cert error, but it may or may not give you the possibility to still view the certificate causing the error.

 

Thanks @ARC1020 good info ....

so it looks like the Roommate turned off the Wifi Security cos She forgot the Password then ? that's not good...

 

You won't get an HTTPS certificate warning from turning off WiFi encryption. This is something else.

 

No, it's definitely not the router encryption. The password is still in place. She stated that the problem began a couple days ago, and she contacted AT&T, and discussed the problem with Greg, the account holder. She stated they were unsuccessful in fixing the problem. According to the AT&T rep she spoke to, there has been "inappropriate activity" on the account, so they placed a "block" on it. Our guess is someone is downloading copyrighted material. What baffles me is that they didn't block torrenting sites, but instead blocked Google.com, YouTube, Facebook, Reddit, and various other social media sites. Oddly enough, I checked out a few well-known torrent sites, and I can access them. I can also access Bing and Yahoo. So Google searches are not allowed, but torrent sites are? Makes no sense.
