How to fix this?
Here are four fixes you can try out.
Restart your router
Power cycling your network equipment is the fix to more issues than you can think. More often than not, connectivity issues can be caused by an underlying bug in your router and can be fixed by rebooting.

Check 9anime’s server status
The next thing to do is to check if 9anime is online and functioning. You can use third-party websites like Isitdownorjustme or Updownradar to check if something’s wrong with the website. If there’s a problem on 9anime’s end, you will have to wait until they can resolve the situation.
Clear your browser’s data
Corrupt files in your cache or otherwise can cause this error as well. Clear them out to see if you can get Chrome to work.
Step 1: Type in chrome://settings/clearBrowserData in your browser’s address bar and hit Enter.

Step 2: Select the cache and cookies options and make sure the Time range is set to All time. Click on the Clear now button to clear out all the data.

Restart the browser once done and 9anime should start working as usual.
Disable extensions
Corrupt or malfunctioning extensions often cause a lot of problems, including this one.

Head over to chrome://extensions and try disabling all your extensions to check if the browser starts functioning as normal again; if it does, enable them one by one until you have all the essential extensions working again.
