Welcome Janis,
I understand how frustrating it can be when your Windows 11 PC is loading certain websites (such as chatgpt.com and x.com) very slowly or getting stuck, while those same websites load normally on other devices and other websites work fine on this PC.
To help resolve this as quickly as possible, could you please confirm the following details:
- Are you using a home network with a router, or are you connected through a VPN or proxy on this PC?
- Does the issue still occur when you connect the PC to a different network, such as a mobile hotspot?
In the meantime, you can try the workaround steps to troubleshoot the issue:
Option 1: Restart the network stack.
- Open Settings > Network and Internet > Advanced network settings
- Select Network reset, then restart the PC
Option 2: Disable IPv6 temporarily to test.
- Go to Settings > Network and Internet > Advanced network settings
- Select your active adapter > Edit > Uncheck Internet Protocol Version 6 (IPv6)
- Restart the PC and test the affected websites
Option 3: Flush and renew DNS.
- Open Command Prompt as administrator from the Start menu
- Run the following commands one by one:
-
ipconfig /flushdns -
ipconfig /release -
ipconfig /renew
-
Option 4: Temporarily disable third‑party security or network filtering software, if installed, and test again.
Option 5: Check system files.
- Open Command Prompt as administrator from the Start menu
- Run:
sfc /scannow - Restart after completion
