Various SSLErrors on twitch.tv

[gbnrileuhg1]

Make sure you are using the latest version: run youtube-dl --version and ensure your version is 2018.03.20. If it's not, read this FAQ entry and update. Issues with outdated version will be rejected.

• I've verified and I assure that I'm running youtube-dl 2018.03.20

Before submitting an issue make sure you have:

• At least skimmed through the README, most notably the FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones
• Checked that provided video/audio/playlist URLs (if any) are alive and playable in a browser (I didn't test the specific channel pages because recently their JS seriously sucks (that's why I'm using youtube-dl to get the URLs instead of only for fetching the videos), but twitch.tv is reachable in Firefox)

What is the purpose of your issue?

• Bug report (encountered problems with youtube-dl)
• Site support request (request for adding support for a new site)
• Feature request (request for a new functionality)
• Question
• Other

If the purpose of this issue is a bug report, site support request or you are not completely sure provide the full verbose output as follows:

The first few logs are from youtube-dl version 2018.03.14. First, a log with an error I didn't stumble upon with the -v flag:

In the following logo it worked for the frist three files. As I'm not interested in more results I pressed Ctrl+C after those. I'm not sure whether the error came before or after pressing Ctrl+C, but propably before, as "^C" is printed after the next prompt.

This one is still from version 2018.03.14 to show this fifth error also occured in this version (and this log is not verbose, because I didn't notice the error in the previous one at first and expected the whole thing to have just been a short hiccup):

ERROR: Unable to download JSON metadata: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:2217) (caused by SSLError(1, '[SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:2217)')); please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see  https://yt-dl.org/update  on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

And finally, a log from version 2018.03.20 so this isn't a reason to close as invalid:

Description of your issue, suggested solution and other information

As the logs above suggest, I'm getting various SSLErrors when trying to download from twitch.tv. It does work sometimes though, i.e. after that last error I tried it again and got a list of >75 Videos before I aborted.
