Post the full output of youtube-dl when run with -v, i.e. add -v flag to your command line, copy the whole output and post it in the issue body wrapped in ``` for better formatting. It should look similar to this:

$ youtube-dl -v <your command line>

Do not post screenshots of verbose log only plain text is acceptable.

The output (including the first lines) contains important debugging information. Issues without the full output are often not reproducible and therefore do not get solved in short order, if ever.

Looks like udemy serves you a webpage of different layout. What's your location?

[mkranthikmr]

India... Telanga... If you don't mind.. Can you share the link from where you can download?

[mkranthikmr]

• Telangana..

[dstftw]

Try using some proxy with --proxy.

[mkranthikmr]

Tried.. No use...

[dstftw]

Post verbose log.
