ERR_CONNECTION_TIMED_OUT
ERR_CONNECTION_TIMED_OUT in Google Chrome: the connection takes too long
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
Chrome tried to connect to the site and the wait timed out. It may be a slow connection or a busy site. Check whether other sites load, restart the router if they all fail, and try another network.
Safety first
Stop and check this first
- If the site fails only from your network, restarting the router again and again will not fix it: note the times and take them to your provider.
Safe checks you can perform
- How fast other sites load
- Modem and router
- The site from another network
- Server load and reachability
Leave these tasks to a qualified professional
- Do not attempt this professional task: Line check by the provider
- Do not attempt this professional task: Diagnose the site's server
What a technician must be able to justify

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Line check by the provider
What they doThe internet service provider checks the line and router if timeouts affect every site.
They must show youthe result of their line test.
In writingfault found and fix applied.
Diagnose the site's server
What they doThe operator matches the time of the report with server load and server and firewall logs.
They must show youmetrics or logs from that time.
In writingcause found and change applied.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
How fast other sites load
- Who:
- you.
- How:
- open several well-known sites and see whether they load normally.
- Result that matters:
- whether the slowness is general or only this site.
- If everything is slow or fails:
- it points to your connection; continue with the router.
- If the others load fine:
- rule out your general connection and test this site from another network.
- Evidence to keep:
- time and sites tried, with their result.

Modem and router
- Who:
- you.
- How:
- restart the modem and router as Chrome Help suggests and test again once the connection lights are steady.
- Result that matters:
- whether sites load after the restart.
- If they load again:
- the router or the line was the source.
- If every site still fails:
- contact your internet service provider with the times you noted.
- Evidence to keep:
- times of the restart and of later failures.

The site from another network
- Who:
- you.
- How:
- open the same address on your phone using mobile data, with Wi-Fi off.
- Result that matters:
- whether the timeout repeats outside your network.
- If it also times out:
- it indicates the site is busy or down; wait or tell the operator.
- If it opens on mobile data:
- the block is in your network or device; check firewall and antivirus.
- Evidence to keep:
- a screenshot of the error on each network with the time.

Server load and reachability
- Who:
- the site operator.
- How:
- review server load and logs at the time of the failure, and test a connection to the public port from an outside network.
- Result that matters:
- whether the server accepts the connection in time.
- If it does not answer from outside:
- it indicates overload, an outage or a filter dropping packets before the server.
- If it answers normally from outside:
- the break is on the visitor's path; ask for their network and time.
- Evidence to keep:
- load metrics and the outside test result with the time.
Only the site operator. Restarting production services must follow the team's procedure; if you do not run it, stop and report.

Where this code applies
A code is meaningful only inside the right product and version context.
Primary scope
- System
- Software and digital services
- Brand
- Google Chrome
- Product type
- Web browsers
Known code variants
- ERR_CONNECTION_TIMED_OUT
- ERR_CONNECTION_TIMED_OUT (-118)
- ERR_CONNECTION_TIMED_OUT Chrome
- net::ERR_CONNECTION_TIMED_OUT
What it means
Chromium defines ERR_CONNECTION_TIMED_OUT (-118) as a connection attempt that timed out; it sits in the connection error range. Chrome Help says the page took too long to connect and that your connection might be too slow or the page too busy. It also lists firewall, antivirus and router among the factors behind connection errors. The code does not separate your network, your provider's network and the server: you separate them by testing from another network.
Warnings and stop conditions
- Loweditorial warning
If the site fails only from your network, restarting the router again and again will not fix it: note the times and take them to your provider.

Symptoms and causes
Probable causes · in order
- Slow or unstable connectionPossible
If other sites are also slow or fail, the problem is in your network, router or provider.

- Busy or down sitePossible
If only this site fails, also from another network, the server is not answering in time.
Evidence: Google Chrome Help - Get help with common error messages in Chrome
- Firewall or antivirus holding the connectionPossible
Suspect it when the site opens from another device on the same network but not from this one.
