"Error: Not a window" via Instagram App Browser


I am getting the error "Error: Not a window" in our sentry logs. This error is only occurring for users using Instagram's browser.

In sentry, it says that the "function" for the exception is "setTimeout" and "addEventListener."

The sentry trace isn't really providing any other useful information as far as I can tell. I am not even sure whether or not users or noticing this problem / if it is affecting them because I can't reproduce it on my device, even with the instagram browser and the same OS.

Any knowledge on the instagram browser and how it behaves would be awesome, we've had some problems in the past with popups in their browser as well.

1. Restart Your Internet Connection

Even if you have a working internet connection, the “This site can’t be reached” error can appear if there’s any type of error with it. Although it may sound too simple, restarting your router or modem can often resolve this problem quickly.

Since restarting your connection usually only takes a minute or two, this is the first solution you should try. Most internet service providers (ISPs) will recommend disconnecting your router’s power cable and waiting a full minute before reconnecting it. Once it’s back on, wait for your internet connection to reset, and then try re-accessing the website.

2. Disable Your Firewall and Antivirus

In many cases, your operating system’s (OS) built-in firewall — or whichever software you use — can block pages aggressively and prevent your computer from establishing a connection to them. The easiest way to figure out if that’s the problem is to temporarily disable your firewall and antivirus software, and try visiting the site again.

Depending on what OS you’re using, you’ll need to follow a different set of steps to disable the built-in firewall. You can use the following articles for guidance:

  • How to Disable the Windows firewall
  • How to Disable the Firewall in macOS

As for disabling your antivirus software, your settings will depend on the tool you’re using. In our experience, it’s rare for your firewall to block you from loading a website unless it’s truly dangerous.

If disabling your firewall and antivirus software doesn’t work, it’s time to try a different method. Don’t forget to reactivate both before moving on.
