After investigating this particular issue, it turns out that there are several different underlying causes that might be triggering this error code. Here’s a list of scenarios that are most likely occurring: Now that you are familiar with every potential culprit that might produce this error, here are a couple of methods that will most likely allow you to fix the issue:
Method 1: Checking the status of ClipGrab
Keep in mind that since Clipgrab is developed independently, it’s prone to break every time a supported platform like YouTube, Vimeo, Dailymotion, or Facebook makes a change that breaks the download protocol. Given the small team behind it, you can expect the 403 error to occur until the developers react and adapt to the changes – This has happened a few times in the past, and typically the issue was resolved in a couple of days. So before trying any of the other potential fixes below, start by visiting the official Twitter account of ClipGrab and checking for any official announcements regarding an ongoing issue. Another good place to check for an ongoing ClipGrab issue is the official support forum of ClipGrab – If you find that other users are currently reporting the same kind of issue you’re getting, you can safely conclude that the issue is beyond your control. On the other hand, if you find no evidence that the 403 error in ClipGrab is currently experiencing server issues, move down to the first potential fix below.
Method 2: Updating ClipGrab to the latest version
If the previous investigation has found that the issue cannot be attributed to a server issue, the next potential culprit you should investigate is your current ClipGrab build. As stated previously, ClipGrab is prone to break whenever YouTube, Vimeo, and the rest of the supported platforms make a change in their streaming protocol. But even if the developer fixes the issue promptly, you still need to get the changes to show up on your PC or Mac. And given that ClipGrab has no AutoUpdate function, the only way to ensure that you’re running the latest version is to uninstall the current one and download the latest from the official channel. To accommodate both user bases, we’ve put together 2 sub-guides that will show you how to do this on Windows and macOS:
A. Updating ClipGrab on Windows
B. Updating ClipGrab on macOS
If the same problem is still occurring, move down to the next potential fix below.
Method 3: Preventing the Security suite interference (Windows 10 Only)
If you’re experiencing the 403 error on a Windows computer, there’s a big chance you’re seeing this problem due to a problem fetching the youtube.dll which is a requirement when grabbing content from YouTube using ClipGrab. But as it turns out, you can expect this download to fail due to the default security suite (Windows Security) flagging the main executable of ClipGrab as a potential security threat due to a false positive. Fortunately, several affected users that were also dealing with this problem have reported that they managed to fix the apparition of this error either by whitelisting the main ClipGrab executable or by disabling the real-time protection when using ClipGrab. To make matters easier for you, we’ve created 2 separate sub-guides to accommodate both scenarios:
A. Disabling the real-time protection
B. Whitelisting ClipGrab’s executable
