ERR_TIMED_OUT means Chrome tried to connect to a website but did not receive a response quickly enough. Unlike errors that fail immediately, this one usually appears after the page sits loading for several seconds. The cause may be weak Wi-Fi, an overloaded router, a firewall, a VPN, a proxy, or a slow website server.
Does this affect you?
Use this for Chrome, Edge, and other Chromium browsers on Windows or Mac when a page eventually shows ERR_TIMED_OUT after trying to load for a while.
Check the basics first
Connection quality causes more timeouts than browser settings do.
- Try a known website such as google.com. If it also times out, troubleshoot the connection.
- Check Wi-Fi signal strength. Move closer to the router or test with Ethernet if possible.
- Restart the router by unplugging it for one full minute, then waiting a few minutes after plugging it back in.
- Hard reload the page with Ctrl+Shift+R on Windows or Cmd+Shift+R on Mac.
Rule out a firewall or antivirus block
A security rule can block a connection long enough for Chrome to report a timeout.
- On Windows, open Windows Security > Firewall & network protection and temporarily turn off the firewall for the active network.
- On Mac, open System Settings > Network > Firewall and temporarily turn it off if enabled.
- Reload the page.
- If it loads, review firewall or antivirus web-shield settings and add a proper exception.
- Turn the firewall back on if it was not the cause.
Disable a VPN or proxy temporarily
VPN and proxy servers can stall or route traffic through overloaded locations.
- Quit any VPN app or browser VPN extension completely.
- In Chrome, open Settings > System > Open your computer proxy settings.
- Make sure no proxy is configured unless you intentionally use one.
- Reload the site.
- If the page works, reconnect the VPN to a different server and test again.
More control
One site may be down
If only one site times out while others load, the site server may be slow or offline. Check from another device or use a status checker, then try again later.
Watch for Wi-Fi interference
Intermittent timeouts can come from distance, thick walls, crowded Wi-Fi channels, or too many devices. Ethernet is a useful test because it removes wireless interference from the picture.
Reduce router load
Routers can struggle with many active devices and connections. Restarting helps, but disconnecting unused smart TVs, phones, and smart devices can also reduce timeouts.
Check the hosts file
A custom hosts-file entry can point a site to an address that never responds. On Windows, check C:WindowsSystem32driversetchosts. On Mac, check /etc/hosts and remove old entries for the affected site.
