I encountered an issue where all Google AdSense ads on this site displayed “googleads.g.doubleclick.net took too long to respond.”, so I’ll share the solution.

Background: googleads.g.doubleclick.net took too long to respond.

The ads on this site displayed “googleads.g.doubleclick.net took too long to respond.”, so I’ll share the method I used to investigate and resolve it.

Investigation Method: Wi-Fi ON/OFF

When I tried connecting with both 4G network (IIJmio) and Wi-Fi respectively:

• 4G: Normal Google AdSense ads displayed
• Wi-Fi: googleads.g.doubleclick.net took too long to respond.

Solution: Restart the Router

After troubleshooting the issue, I found that the “googleads.g.doubleclick.net took too long to respond.” problem only occurred when connected via Wi-Fi. I restarted the Wi-Fi router, and the issue was successfully resolved.

Above, I resolved the Google AdSense “googleads.g.doubleclick.net took too long to respond.” issue.

That’s all from the Gemba.
