1. Use Grammarly on a different browser
This issue may also occur due to browser incompatibility issues. The quickest method to check if this is the case is to simply test Grammarly on a different browser.
This browser is excellently optimized for various hardware and software configurations. This virtually eliminates the risk of experiencing any browser compatibility problems.
As a matter of fact, we’ve been using Grammarly on Opera for a few months now and we didn’t encounter any issues whatsoever.

2. Clear your browser’s cookies
- First, click the Customize Google Chrome button to open the browser’s menu.
- Select Settings to open the tab shown directly below.
- Scroll down to the bottom of the page tab and click Advanced.
- Select Clear browsing data to open the options shown directly below.
- Select the Cookies and other site data option.
- In addition, select Cached images and files setting to clear the cache.
- Press the Clear data button.
Additionally, if you want to free up even more disk space, you should try CCleaner. Not only will this tool clean your PC of all cookies and cache files, but it will eliminate all kinds of residual data plaguing your PC.
The interface is very intuitive, and all you need to do is run a scan, and let CCleaner do its job.

Our grammar robot is recharging is another Grammarly error message that you might see upon opening the editor. That error message can be due to corrupted cookie files. Thus, clearing cookies might fix Grammarly.
3. Check browser compatibility
Thus, the editor isn’t much good for Opera, Maxthon or Vivaldi users. So switch to one of the compatible browsers if required.
4. Update Your Browser
- Click the Customize Google Chrome button at the top right of the browser’s window.
- Select Help to expand its submenu.
- Then click About Google Chrome to open the tab shown directly below.
- Google Chrome will then check for updates and update automatically. To finish the updating the browser, press the Relaunch button.
Grammarly isn’t compatible with every Chrome, Explorer, Edge, Safari and Firefox version. So outdated versions of those browsers aren’t compatible with the editor either.
As such, make sure you’re utilizing the latest browser versions to ensure compatibility.
5. Reduce the document length
If you can’t upload a document to Grammarly, it might be the case that the file eclipses four MB. Four MB is the maximum file size for documents you can upload to Grammarly. Also note that you can’t upload documents with more than 60 pages.
Reducing the document’s length will remove pages from it and cut its file size. Consider saving half of your original document in a separate file if it currently eclipses the maximum page number for Grammarly.
Then you can probably upload both halves of the document to Grammarly separately, and merge them together again after editing them.
6. Turn off third-party antivirus software
The Grammarly server relies on WebSocket connections. Your third-party antivirus utility might be blocking WebSockets if you see a Grammarly error message that states, Error checking is temporarily unavailable.
As such, temporarily turning your antivirus software off might fix the Error checking is temporarily unavailable error. To disable an antivirus utility, you can usually right-click its system tray icon and select a disable or turn off option.
Alternatively, have a look through the antivirus utility’s settings tab on its primary window to select a disable setting from there.
7. Turn Off the Windows Defender Firewall
Some firewalls can also block WebSockets and Grammarly internet addresses. Thus, temporarily turning the Windows Defender Firewall off before you open Grammarly in browser might also fix “Not connected” notifiers that pop up within its editor.
That will ensure WDF isn’t blocking the editor in any way. This is how you can switch off the Windows Defender Firewall in Win 10.
- Press the Type here to search button on the taskbar to open Cortana.
- Enter the keyword ‘Windows Firewall’ in Cortana’s search box, and select Windows Defender Firewall to open its Control Panel applet.
- Click Turn Windows Defender Firewall on or off to open the settings shown directly below.
- Select both the Turn off Windows Defender Firewall network settings there, and click the OK button.
8. Reset your browser
Grammarly compatibility issues can also arise from browser extensions and plug-ins. So removing browser add-ons is another potential fix for Grammarly not working.
The quickest way to do that is to reset your browser, which will remove (or at least disable) all its extensions. Furthermore, that will clear browsing data, which can also fix Grammarly error messages.
Follow the guidelines below to reset Google Chrome:
- Enter chrome://settings/ in Chrome’s URL bar, and press the Return key.
- Click Advanced to expand the Settings tab.
- Scroll to Reset and clean up at the bottom of the Settings tab.
- Click Restore settings to their original defaults to open a Reset settings box.
- Press the Reset settings button to restore Chrome to its original configuration.
So updating your browser, turning antivirus software and the Defender Firewall off, reducing document lengths and erasing browser cookies will probably fix most Grammarly web app errors.
