Sounds like a problem with your Internet connection. Contact your ISP for help. One thing you could try is changing your DNS to a known working one: You can manually change your DNS to Cloudflare's, which has a good reputation for performance and reliability. To do this on Windows 11, there's two main ways: 2a. Windows 11 Settings app Step 1: Open the Settings app and click the "Network & Internet" tab Step 2: Click "Properties" at the top Step 3: Beside "DNS server assignment", click edit and change to manual Step 4: Switch on both IPv4 and IPv6 Step 5: Enter the following settings for IPv4: Preferred DNS IP: 1.1.1.2 DNS over HTTPS: On (manual template) DNS over HTTPS template: https://security.cloudflare-dns.com/dns-query Fall-back to plaintext: On Alternative DNS IP: 1.0.0.2 DNS over HTTPS: Off Step 6: Enter the following settings for IPv6: Preferred DNS IP: 2606:4700:4700::1112 DNS over HTTPS: On (manual template) DNS over HTTPS template: https://security.cloudflare-dns.com/dns-query Fall-back to plaintext: On Alternative DNS IP: 2606:4700:4700::1002 DNS over HTTPS: Off Step 7: Click save and restart your PC. It's important you do both IPv4 and IPv6, as if one is invalid it will cause issues. 2b. Control Panel Network and Sharing Centre Step 1: Press Start, search for "Control Panel" and open it Step 2: Click "Network and Internet" and then "Network and Sharing Centre" Step 3: On the right, click the link next to "Connections:" then click "Properties" Step 4: Click "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties" Step 5: Click "Use the following DNS server addresses" and enter the following addresses: Preferred DNS server: 1.1.1.2 Alternate DNS server: 1.0.0.2 Step 6: Click OK then "Internet Protocol Version 6 (TCP/IPv6)" and "Properties" Step 7: Click "Use the following DNS server addresses" and enter the following addresses: Preferred DNS server: 2606:4700:4700::1112 Alternate DNS server: 2606:4700:4700::1002 Step 8: Click OK on the remaining windows and restart your PC. It's important you do both IPv4 and IPv6, as if one is invalid it will cause issues. How do I know if this worked? Go to https://1.1.1.1/help and it should say you're connected to 1.1.1.1. If it doesn't, open PowerShell, run `Clear-DnsClientCache`, reboot and try again.
