Windows 10: Privacy error when connecting through ethernet

When i'm connecting through wi-fi everything works, but when i connect ethernet cable on every browser i get privacy errors. (for. Example on chrome net:: ERR_cert_authority_invalid, on mozilla ssl_error_bad_mac_read). None of applications can connect to internet too. I tried things like changing dns, some other popular solutions for this problem, and it doesn't work. Ethernet cable isn't a problem, i checked it. I also done clean windows install. I checked diffrent drivers for network card.
Can someone help me?

Ethernet Doesn't Have a valid IP configuration - Able to connect through wireless

I am unable to access my internet through on my PC through Ethernet and when I try troubleshooting it says - Problem Found - "Ethernet" doesn't have a valid IP configuration.

I tried various methods to solve the error but without any success. Some methods I used are as follows:

1. Disabling Fast Boot
   
2. Resetting my Router manually
   
3. Going to Command Prompt and typing "ipconfig /release" which gives the message - " An error occurred while releasing Interface Ethernet : An address has not yet been associated with the network endpoint."
   
4. Going to Command Prompt and typing "ipconfig /renew" which gives the message - "An error occurred while renewing interface Ethernet : An attempt was made to access a socket in a way forbidden by its access permission"
   

In above steps I used Command Prompt with Administrative Privileges.

I suspect that my PC may have been infected by a virus which is blocking my internet.

Note that I am able to connect to the Internet through Wireless Connection on my mobile device (on which I am accessing this site)

Kindly help

 

Only IPV6 connection through ethernet, ipv4 not connecting (Through google fiber, no router/modem)

1. I was last able to access sites two days ago at night. Yesterday, all ipv4 connections failed.

2. I last patched to the latest version of windows 4-5 days ago, but internet was working fine for 2-3 days after the patch.

3. I'm using chrome, I've tried Edge to no avail.

4.

• I plugged a different computer into the same cord and ethernet port, got the same problem
• I plugged the this computer with the same cord into a different ethernet port, same problem
• I plugged this computer with a different cord into the same ethernet port, same problem

I believe it may be an issue with the building's ethernet itself. However, using a wireless connection to a router that is plugged into the building ethernet through a third port works fine.

I also tried all the steps linked there, no success. I have also tried forcing static ip's for IPV4 connection, but no success there either.
