Description

Hi, mgtv (mgtv.com) is a website in China mainland, and I am also in China mainland, so I have to add "--no-geo-bypass" parameter, or it will end up in download error.

I guess it will use --geo-bypass on this website by default? This result in a IP outside China mainland and cause problems.

However, this "An extractor error has occurred." has nothing to do with the parameter, because there was no problem last week (accurately on Aug. 16, UTC+8 timezone).

Same issue inside China!

Same issue in Europe with mgtv. Mgtv was working with youtube-dl version 2020.07.28 until quite recently (with the --no-geo-bypass option, and at least sometimes needing the --cookies option).

In my case using:
[debug] youtube-dl version 2020.07.28
[debug] Python version 3.8.5 (CPython) - macOS-10.15.6-x86_64-i386-64bit
[debug] exe versions: ffmpeg 4.3, ffprobe 4.3, rtmpdump 2.4
