If you can’t access Prezi properly, whitelist Prezi domains in your ad blocker or firewall, then refresh the editor.
Why does Prezi look offline when my internet works?
When Prezi says you’re offline, an ad blocker or firewall filter may be blocking Prezi services.
This can make parts of the Prezi editor appear greyed out or fail to load.
Ad blockers can block “ad-like” network requests. That can affect Prezi even if you’re not viewing ads.
How do I fix Prezi offline issues caused by an ad blocker?
When Prezi looks offline, whitelist Prezi in your ad blocker, then reload Prezi.
- Open your ad blocker settings.
- Find the allowlist/whitelist option (often called “Allowlist,” “Exceptions,” or “Trusted sites”).
- Add the domains below.
- Refresh the Prezi editor tab.
- Try opening your presentation again in Prezi.
What domains should I allowlist to keep Prezi working?
Allow pop-ups and allowlist these domains in your ad blocker or firewall software:
- *.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
Tip: Using *. means all subdomains are included.

How do I test if my browser is causing the issue?
