Sometimes shared or managed networks or devices can have firewall or security settings that prevent the site from running or displaying correctly, causing you to receive a 404 error. If you aren’t able to upload any media, or if parts of the website aren’t working while using your workplace or school network or device, this may be the cause.
You can ask your IT department or network administrator to whitelist Animoto, which should resolve this. You can also let them know to ensure full functionality, the following domains should be whitelisted:
*.animoto.com
*.video214.com
Our main site IP ranges: 54.243.143.220 and 54.243.142.92
Once Animoto is whitelisted, that should solve the problem but you can reach out to the Animoto team for further support any time at Help@Animoto.com
