Recently, I have been unable to download YouTube videos using Internet Download Manager (IDM). After utilizing IDM's floating download tool, I was able to detect the download address and add it to IDM, and also acquire the file's size. However, I continue to encounter issues with successful downloads. I suspect that the problem may be related to the settings of my VPN. I recall that previously, when setting up my VPN, I used a script address with '127.0.0.1' followed by a question mark, as opposed to directly inputting the VPN's IP address and port. I would greatly appreciate any advice or guidance from experienced individuals in resolving this issue.
