ERR_CONNECTION_ABORTED

The connection timed out while sending data: Chrome sent something and never got an acknowledgement, so the connection was aborted.

Chromium's description

A connection timed out as a result of not receiving an ACK for data sent. This can include a FIN packet that did not get ACK'd.

Chrome shows it as net::ERR_CONNECTION_ABORTED, error -103. puppeteer and Playwright report the same name when a page fails to load in Chromium.

Common causes

A network that loses packets, an unstable Wi-Fi or mobile connection.
A firewall, antivirus or VPN that holds back traffic.
A server that is overloaded and stops answering mid-connection.
Wrong MTU settings on a VPN or router.

How to fix ERR_CONNECTION_ABORTED

Reload and try another network.
Turn off VPN, proxy and HTTPS scanning.
Restart the router and reset the network settings.
Site owners: check server load and firewall rules that might drop established connections.

ERR_CONNECTION_ABORTED in the screenshot API

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