Chrome is configured to use a proxy server, but the connection to the proxy failed. The proxy is misconfigured, offline, or blocking the request.
Why this happens

- The proxy server is offline or unreachable
- VPN software left behind broken proxy settings after uninstalling
- Corporate proxy requires authentication but credentials are wrong
- ISP transparent proxy is malfunctioning
How to fix it
