# Chrome: The connection was aborted — ERR_CONNECTION_ABORTED (software on your computer caused it)

**Code:** `ERR_CONNECTION_ABORTED` · **Category:** Browser · **Seen on:** Chrome, Edge, Windows

The connection was aborted on your own computer — usually antivirus, a firewall or VPN software terminating it.

## Meaning

The "aborted" wording tells you the local network stack ended the connection, not the remote server. Security products that inspect HTTPS, a VPN client and Windows firewall rules are the usual culprits, as are corrupted Winsock entries.

## Common causes

- Antivirus or firewall HTTPS scanning
- VPN or proxy client interfering
- Corrupted Winsock/TCP-IP settings
- Hosts file or security software blocking the site
- Unsupported or broken TLS settings on the device

## Quick fix

1. Pause the antivirus web shield and VPN and test
2. Reset Winsock: `netsh winsock reset` and reboot
3. Check the hosts file for entries blocking the site

## Detailed fix by platform

### Windows

1. `netsh winsock reset` and `netsh int ip reset` then reboot
2. Check `C:\Windows\System32\drivers\etc\hosts`

### Chrome

1. Try incognito or `chrome://net-internals/#sockets` → Flush socket pools

## How to diagnose

1. **Scope** — One site or all sites?
2. **Security** — Antivirus/VPN active?
3. **Hosts** — Any blocking entries?
