ERR_SOCKET_NOT_CONNECTED

Q: How do I fix ERR_SOCKET_NOT_CONNECTED?

Flush the socket pools at chrome://net-internals/#sockets and the DNS cache at chrome://net-internals/#dns.

Chrome tried to use a network connection (socket) that was no longer connected. It points to a problem on the local machine or network more than on the website.

Chromium's description

The socket is not connected.

Chrome shows it as net::ERR_SOCKET_NOT_CONNECTED, error -15. puppeteer and Playwright report the same name when a page fails to load in Chromium.

Common causes

A stale connection pool after the network changed or the computer woke from sleep.
A broken network stack, VPN or proxy setting.
DNS problems that leave Chrome with dead sockets.

How to fix ERR_SOCKET_NOT_CONNECTED

Flush the socket pools at chrome://net-internals/#sockets and the DNS cache at chrome://net-internals/#dns.
Restart Chrome and the network connection.
Switch to a public DNS server such as 1.1.1.1.
Reset the network settings (Windows: netsh winsock reset).

ERR_SOCKET_NOT_CONNECTED in the screenshot API

When the page itself fails to load with ERR_SOCKET_NOT_CONNECTED, the API answers 502 with the message The target website could not be loaded (ERR_SOCKET_NOT_CONNECTED). (target_unreachable). Not billed.

Only the page's own load can fail a render. An image, script or frame of the page that fails with a network error does not: the page is captured as the browser shows it without that resource.
