ERR_CONNECTION_RESET Error

Fix 'ERR_CONNECTION_RESET' or 'net::ERR_CONNECTION_RESET' errors in Chrome and other browsers. Learn why TCP connections are reset and how to fix them.

What Does This Error Mean?

The ERR_CONNECTION_RESET error means a TCP connection was forcibly closed (reset) by the server or an intermediate network device. Unlike a normal connection close, a reset indicates an error condition — the connection was terminated without completing the HTTP request/response cycle.

Common Causes

Firewall or security software blocking the connection

Server crashed or was restarted while connections were active

Load balancer or reverse proxy dropping connections

SSL/TLS handshake failure causing connection reset

Browser or OS network stack issues

VPN or proxy service interfering with the connection

How to Fix It

Check firewall and antivirus

Temporarily disable security software to see if it's blocking the connection.

# Windows: check Windows Defender Firewall
wf.msc

# Linux: check iptables
sudo iptables -L -n

# Check if security software is intercepting HTTPS
# Try accessing the site from a different network (e.g., mobile hotspot)

Clear browser cache and cookies

Corrupted cached data can cause connection issues.

# Chrome: Clear cache
chrome://settings/clearBrowserData

# Or use incognito mode to test
# If it works in incognito, cache/cookies are likely the issue

Flush DNS and reset network

Reset the local network stack.

# Windows
ipconfig /flushdns
netsh winsock reset
netsh int ip reset

# macOS
sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder

# Then restart browser
