Browers can't connect to the internet

Question

Browers can't connect to the internet

frank fileccia 0

Windows 10 Pro

Version 22H2

I have an online radio station running on an HP Elitedesk . Everything was working fine until I moved to a new location. At that point all browers (Chrome, Firefox, Edge) stopped accessing the internet. FTP still works, and the broadcast software still works. Windows update does not work.

The computer is on a network with 3 laptops. All of them can connect to each other.

First I get a "your connection is not private" error, Clicking on Advanced and Proceed to... I get ERR_CONNECTION_RESET on all browers. It doesn't matter what site I try to go to

I changed to a different ISP when I moved. Thinking that might be the problem I changed back to the original ISP.

I can access the router controls through the computer.

I have tried every solution I can find on the internet, reset network, reset DNS, etc. I went into the microsoft firewall manager and changed the rules so everything has access, incoming and outgoing. (I know, stupid thing to do). The HOST file is empty, so nothing is blocking it there.

The LAN port is permanently attached to the motherboard. Thinking there may be some physical damage, I bought a PnP LAN card. Same problem.

I am desperate to get this problem fixed. It's been happening since June. Any ideas?

Dear frank fileccia
Thanks for reaching out to Microsoft Q&A Forum!

I've reviewed the incident regarding your browser and Windows Update connection issues, specifically the "Your connection is not private" and ERR_CONNECTION_RESET messages. The symptoms you're seeing often indicate an incident with secure connection protocols (SSL/TLS), likely due to an incorrect system time setting or interference from third-party security software. A proxy, VPN, or SSL-interception setting (or corrupted system root certificates) is interfering with HTTPS traffic only. Non-browser apps (FTP, broadcast) use different protocols, so they’re unaffected.

To guide you best, could you let me know:

Do you use any antivirus with HTTPS scanning or a corporate proxy?
Can you share the output of ipconfig /all (redact public IP)?
In Edge, press F12 > Console > any specific error after ERR_CONNECTION_RESET?

In the meantime, please consider trying my suggestions for Windows 10 and keep me updated with anything news from it:

Preparation and requirements:

Ensure the date, time, and time zone are absolutely correct on your PC.
Completely disable or uninstall any non-Microsoft security software (like an external antivirus or VPN client) just to test if it's intercepting your secure traffic. Do not browse the internet unprotected for long. Re-enable or reinstall after testing.

Afterward, please follow this instruction and let me know anything new from it:

Win + R > Type: inetcpl.cpl > Connections > LAN settings > Uncheck all boxes (especially “Use a proxy server”) > Click OK > restart browsers
Open [PowerShell] from search bar > [Run as Administrator] > Run:
- certutil -setreg chain\EnableWeakSignatureFlags 0
- certutil -generateSSTFromWU roots.sst
- Double-click roots.sst > install all
Search [Command Prompt] on search bar > [Run as Administrator] > Run:
- netsh winsock reset
- netsh int ip reset
- Restart PC
Open [Control Panel] > [Network and Internet] > [Internet Options] > Go to the [Connections] tab > [LAN] settings:
- ensure "Use a proxy server for your LAN" is unchecked. Also, on the Advanced tab, click "Restore advanced settings."

Disclaimer: Incorrect proxy settings will block all browser and Windows Update traffic, while still allowing non-HTTP traffic like FTP.

I followed your directions for inetcpl.cpl

Proxy server - use a proxy server was checked. i unchecked it and the browsers didn't work. I opened inetcpl.cpl again and the proxy server was checked again. it seems it can't be cleared

Powershell run as admin certutil was run, there was not option to double click on roots.sst. The cert manager shows 507 certificates

the netsh resets had no effect

use a proxy server remanins checked and still cannot be unchecked

Dear frank fileccia

I appreciate you providing the detailed feedback and diagnostic information, especially the output of ipconfig /all. This is very helpful and narrows down the focus considerably! An invalid proxy is being enforced (likely a blank or localhost entry), causing the system to reset the connection for secure sites. This behavior indicates a deeper configuration issue, possibly a locked registry setting or remnants of software that are continuously forcing the use of a proxy server, even though you uncheck it. This explains why only your secure (HTTPS) and Windows Update traffic is failing, as it's hitting this non-existent or faulty proxy.

Step 1:

Press [Win + R] key, type regedit > press [Enter]

Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

Delete the following values (if they exist) in the right-hand pane:

ProxyEnable

ProxyServer

ProxyOverride

==> If it exists, check the value for MigrateProxy; if it's set to 1, change it to 0.

Close [Registry] > Restart PC

Step 2:

Search for [Command Prompt] > [Run as Administrator]

Type and run:

reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /f

reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /f

netsh winhttp reset proxy

Close the Command Prompt.

Step 3:

Press [Win + R] key > type inetcpl.cpl > [Advanced tab] > Click [Reset] (twice if needed) > [OK] > [Restart]

Thanks. I was able to figure it out

In the registry I changed ProxyEnable = 0 to ProxyEnable=1 and that fixed it

Dear frank fileccia

Discovering that changing ProxyEnable from 0 to 1 fixes the issue, but it keeps resetting on reboot, confirms that the problem is an external process or program forcing that registry value back to 0. A machine-wide policy or hidden startup item reapplies proxy settings on boot.

Please follow this final, targeted step using a Clean Boot to isolate and disable the application that is causing the automatic reset:

Step 1:

Press Win + R, type msconfig > press [Enter] > Go to the [Services]tab > Check the box for [Hide all Microsoft services]> Click [Disable all] > Click [OK] > choose to [Restart] your computer.

Step 2

Download/run full scan with Microsoft Safety Scanner on Microsoft Store > Follow any removal prompts > Restart

Step 3:

[Settings] > [Network & Internet] > [Status] > [Network reset] > [Reset now]

Press Win + R > regedit > Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings

If ProxyEnable exists, set to 0; delete ProxyServer/ProxyOverride

If ProxySettingsPerUser exists, set to 1

Restart PC

Step 4:

If the issue is solved in the Clean Boot state, go back into msconfig ([Services] tab) and re-enable services in small groups (or one by one), restarting the computer each time, until the ProxyEnable value resets to 0 again.

Once you find the service that causes the reset, you can permanently uninstall the related application or disable that specific service to prevent the reset forever.
