Troubleshot

1. Can Not Login​

Recently, some users reported being unable to log in to OnlyFans. This issue also occurs on other websites using CloudFlare Challenge.

To make matters worse, you can't sign in to these websites even on browsers that aren't opened with WhaleDown. This is most likely due to the user's computer being labeled a bot by CloudFlare.

Suggestions

Here are suggestions from Google AI.

  • Clear Browser Data: Delete cookies, cache, and history (Ctrl+Shift+Delete) to remove corrupt data.
  • Use Incognito/Private Mode: This disables most extensions and starts a fresh session, often bypassing the issue.
  • Disable Extensions/VPNs: Privacy, security, or VPN extensions can block Cloudflare's scripts.
  • Try a Different Browser: Test if the issue is specific to your current browser (e.g., try Firefox if Chrome fails).
  • Restart Network/Device: Rebooting your router and computer can resolve IP reputation issues.

2. MediaKeySession Error​

Sometimes the web player shows an MediaKeySession error. Sometimes the player shows lots of snowflakes.

Video Play Error

That means that the video is using Widevine DRM technology to protect it.

This error is due to the hacks WhaleDown uses to obtain the keys to decrypt the video. At this point, you can see the

icon in the Details View of the video in Detector.

Solution

Please ignore this error. Sometimes the video starts playing after refreshing the page.

At this point, WhaleDown should have detected the video and corresponding keys. Please open the Detetor to view the new video item.

3. Can Not Play Video​

No Solution

We're very sorry this bug can't be fixed for the time being.

4. Open Multiple Tabs On Startup​

Sometimes when users launch a browser using WhaleDown, the browser opens multiple tabs. This issue mainly occurs when using Brave Browser or Microsoft Edge.

Generally speaking, this is not a bug. You can change the behavior of the browser by modifying the startup options in the browser settings.

If at this point you notice that WhaleDown is not able to detect any videos, you've accidentally triggered a bug in Detector. This bug is rare and hard to fix.

warning

If WhaleDown can't detect any videos, close all browsers opened by WhaleDown and try again. Everything should be back to normal at this point.

We also recommend using the Google Chrome browser.

5. Slow On Android​

The built-in browser of WhaleDown is based on Android Webview (A pre-installed system component from Google). Our testing found that older versions of Android Webview have poor performance and cause slow web access.

Solution

Please upgrade Android WebView to the latest version.
