Why Windows 10 Blocks some LAN IPs (192.168..)?

Question

- Summarize the problem:

Windows 10 does not allow visiting my local LAN IPs (192.168.1.0/24), and some domains (that are defined in my hosts file). Error shows in all browsers (e.g. form chrome: Firewall or antivirus software may have blocked the connection.)

- what you’ve tried:

1. I tried to check if chrome is allowed by windows firewall and it is.
2. I tried to disable Windows Firewall in my private network and it did not fix it.
3. I tried using another machine on the same router and it works fine, i can access (192.168.1.1 - router).
4. I cleared my DNS cache (to test the modified hosts domains properly) and the browser won't load them. Although PING works as defined in the hosts file.

Answer 1

I found the issue. it was my VPN app making my laptop from my lan as (invisible feature)

Answer 2

hi it seems some thing block your subnet.if you didnot do any special config on your win10 please test these :

1. Disable all 3 firewall(for a short time to tshoot)
2. Flush your DNS(ipconfig /flushdns) if you can not connect them with domain name and arp cache (arp -d *(open cmd with elevetion ))
3. Check if your system IP address is in correct range .
4. Self ping the system (to check if tcp/ip is working right)
5. Check cable and switch connection
6. Ping another system in your subnet
7. Disable/Enable NIC
8. Run this in cmd netsh int ip reset
