ERR_NETWORK_ACCESS_DENIED
Access to the network is denied
What it means
Windows or a security tool blocked the browser's connection before it left the PC.
Common causes
- Antivirus or firewall rule
- A proxy that requires a login
- Browser permissions or a work policy
How to fix it
- Check Windows Security > Firewall & network protection and any third-party firewall for a block.
- Turn off the proxy or set it to the one your network uses: Settings > Network & internet > Proxy.
- Try another browser; if only one fails, reset that browser's settings.
- On a work PC, ask IT: a policy may block the destination.
