Troubleshooting firewalls and security settings

Firewalls or other security software running on your computer might cause difficulties accessing Prezi Next or certain parts of the site. This is particularly likely to be the case if you are using a different computer than the one you normally use or if you have recently upgraded your operating system or security software.

To prevent or resolve issues with viewing or accessing Prezi Next content:

  • Make sure that JavaScript, cookies, and pop-ups are allowed (whitelisted) for prezi.com in both the browser you are using and your operating system's default web browser.
  • Check that this is also the case with any firewall software, browser privacy add-on, or similar software that you may be running on your computer.

Email whitelist

Whitelist these two sending domains (@notify.prezi.com and @email.prezi.com) and the following IP addresses:

  • 50.56.16.69
  • 50.56.16.71
  • 104.130.98.88

Allow pop-ups (whitelist) in your browser privacy add-on or firewall software for following:

  • .prezi.com
  • .static.prezi.com
  • s3.amazonaws.com
  • .prezi.com.s3.amazonaws.com
  • prezi-a.akamaihd.net
  • .preziusercontent.com
  • .youtube.com
  • .ytimg.com
  • .prezicdn.net
  • .cloudfront.net

You can also try using another browser. We recommend using the latest version of Safari, Firefox, Chrome 64, or Edge.
