It can be related to subtitles. If you try downloading via --skip-sub option the problem does not occur (at least for my case). I just want to share it for temporary solution.

that's because --skip-sub skips downloading subtitles, rest the error is more related to requests then udemy-dl, but i checking alternative ways

kshitij9969 commented 5 years ago

Download the subtitles separately. I think a lot of lectures have autogenerated English subtitles and that is creating an issue while downloading(This is mentioned in a few red coloured errors). Use --skip-sub and --sub-only and download the subtitles separately.

Also, run the --sub-only command multiple times it will download all the subtitles that were skipped in the previous iteration. Better put in a batch file and iterate these commands multiple time.

If you have an external hard disk try --output and download the lectures to it. Somehow the download speed surges and subtitles aren't skipped.

Let me know if the correct reason or solution is identified. Thanks.

ghost commented 5 years ago

This error still persists.

sagespidy commented 4 years ago

--skip-sub works

xxzozaxx commented 4 years ago

--skip-sub works

Not always, it works for 2 videos and then the error rise again

bruno-braga commented 4 years ago

Also getting this error. Even using --skip-sub.

viertelb commented 4 years ago

--skip-sub works with python2.7 on macOS. Also, this reduces the amount of files downloaded. Who needs (auto generated) subtitles in English anyway? :) Could be made default.

viertelb commented 4 years ago

Update: --skip-sub worked for a lot of downloads (even when downloading several courses parallel in three terminal screens) but eventually the same error occured. It is possible to load all courses by executing the command several times.

A wild guess: It might be related to the pace with which items are downloaded.

Looks like Udemy is blocking the connections that are behaving suspicious (not falling under normal user behavior)
