Localhost 404 Errors

Question

Last night, I upgraded my Windows 10 Pro to Version 1903 (OS Build 18362.267). Now my localhost applications don't work. They're either saying they can't establish a connection, or are giving 404 errors. For example, I run a Minecraft Server on Multicraft, which calls for localhost, port 80. It worked fine before the update, now it just keeps giving a 404 error. Tried a bunch of netsh stuff, adding Windows services, flushing dns, etc., but nothing seems to work. So frustrating. Sorry I allowed the update. Maybe I'll try to roll it back.

Try to repair your internet connection

Restore all network adapters to repair your connection.

Open the network and Internet settings in the Configuration application.

The quickest way to do this is to right-click or long press the network icon in the notification tray and choose "Open network and Internet settings". The network icon looks different if you have an active cable connection or a wireless connection. The menu that opens is the same. Choose open network settings and the Internet.

On the left side of the Network and Internet settings window, make sure you are in the Status category. Then, to the right, scroll to the end of the configuration list. There, you should see a link called "Restart the network." Click or tap on it.

The Configuration application opens a view called Network Restart, which tells you that "This will remove and then reinstall all your network adapters, and will set other network components to their original settings. You may need to reinstall other software of networks, such as VPN, client software or virtual switches.

If you agree with all that and want to continue restarting your network adapters, click or touch Reset now.

Windows 10 asks you to confirm that you want to reset your network adapters. If you do so, click or touch Yes.

If you went ahead and chose to reset your network adapters, Windows 10 informs you that your computer or device shuts down in 5 minutes. Close the notification and save whatever you are working on before this timer expires.

SmithErikson,

Thanks for your time and explanation.

• --Did the Network Reset you mentioned. --Still getting 404 errors, when attempting to use my Multicraft on localhost, port 80 (Note: My internet works. It's just localhost that doesn't allow my programs to access it on ports 80 or 443. I did go in and make TCP rules to allow that port to be accessed, but to no avail.)

From the link you gave, I also attempted the following operations:

• Did the newtwork troubleshooter, which found no problems.
• Reset the TCP/IP stack
• Released the IP address, which stated, "An error occurred while releasing interface Ethernet: An address has not yet been associated with the network endpoint."
• Renewed the IP address
• Flushed and reset the DNS client resolver cache
• Roll Back the network adapter driver: All drivers were greyed out, indicating there was no drivers that had been updated in the Windows 10 update.
• Turned off the firewalls temporarily
• Restarted computer, to let above changes take effect

Any other suggestions?
