Your cache is the memory your browser uses to quickly load sites without having to wait on the internet connection to do so. If your network is working just fine, the issue may be with your browser’s cache. At this point, if it still isn’t working, go ahead and check your network connections. Once your PC is back up and running, head back over to the WhatsApp Web app in your browser and try your media once again.
And if it does end up fixing it, you’ll save yourself some time so it definitely doesn’t hurt to try. It may not help addressing the WhatsApp download failure, but it’s always best to rule this step out before moving further along in the troubleshooting process. Go ahead and do a full reboot of the computer this time. After restarting your browser, if WhatsApp download problems still persist, then move on to step 3.
It you aren’t able to download files from WhatsApp Web, close your browser and then launch it again. The first tool in even the most advanced IT toolkits is the tried and true method of simply turning it off and then back on again.
If you reconnect to WhatsApp and media is not downloading still, the issue might be with your browser.
