Close all tabs

Sometimes other tabs can conflict with a site’s loading. Try closing all possible tabs and reloading the site. It should load up just fine. You can also try visiting the site in incognito mode.


Disable antivirus and any third-party firewalls

Another thing that should be on your diagnostics list is to temporarily disable your antivirus and check if you can share files through your network. If you’re using any third-party firewalls, they can also cause conflict with network communications under the pretext of keeping you safe. 


Check for updates

If the issue is in Chrome itself, chances are developers might release an update to fix the problem. Regardless, you should always make sure you’ve got the latest version of the browser installed to avoid running into problems that could otherwise be avoided. 

Head over to chrome://settings/help and make sure you’re on the latest update. If you’re not, update immediately and try again. The *Aw snap* error in Chrome should be fixed.
