Description

Tiktok parsing fails every time with “Unable to download webpage: [WinError 10054] An existing connection was forcibly closed by the remote host” error. I tried with different video URLs and also from different countries. The latest official build was used. There was a similar problem in the past (Issue 10084), one of the top developers investigated it but had to close because it did not reproduce. It’d be good to check it the same way now, since the call stack is identical. In the past the problem was with a different site, and now it seems to be 100% reproducible.
