Host: yt-dl.org. is not in the cert's altnames

[TheBrutalSkull]

Mmmmh... help?

Looks like I have the same issue

Connecting to yt-dl.org (95.143.172.170:443)
ssl_client: yt-dl.org: name `yt-dl.org' not present in server certificate
wget: error getting response: Connection reset by peer

and while youtube-dl -v -U:

CertificateError: hostname u'yt-dl.org' doesn't match either of '*.aries.uberspace.de', 'aries.uberspace.de'

ERROR: can't find the current version. Please try again later.

For those who are looking for a temporary workaround with cURL: you can turn off cURL's verification of the certificate, using the -k (or --insecure) option.

Please note that as the option said, it is insecure. You shouldn't use this option because it allows man-in-the-middle attacks and defeats the purpose of HTTPS; downloading directly from the yt-dl.org site would be a safe alternative.

I saw that, and like you said, it's not recommended... So I'm searching for another solution for that... I'm wondering if it's a problem from my code or directly from yt-dl

[JaredStemper]

Often this is an issue with the host (yt-dl.org) and they will need to fix their certificate. As I mentioned, downloading directly from their site is a secure alternative.

I downloaded my files on their website, so I don't think this the solution. I think I will wait to see if it's solve. By the way, I use this host for discord bot ^^

I had the same certificate error as you and sula7 using the cURL/wget command, but I was able to download the tar file from yt-dl to a new virtual machine and use it to successfully download a video from Youtube. So I don't believe their current version is at fault, but rather certificate handling.

For those that might not want to bother with the tar file, quick copy-paste, referencing the 'latest' release from github:

Hardcoded:

sudo curl -L https://github.com/ytdl-org/youtube-dl/releases/download/2021.02.10/youtube-dl -o /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

Alternatively, getting the latest (credits: https://gist.github.com/steinwaywhw/a4cd19cda655b8249d908261a62687f8#gistcomment-3199552) :

curl -s https://api.github.com/repos/ytdl-org/youtube-dl/releases/latest \
| grep 'browser_download_url.*youtube-dl"' \
| cut -d : -f 2,3 | tr -d \" \
| xargs -n 1 sudo curl -o /usr/local/bin/youtube-dl -O -sSL

sudo chmod a+rx /usr/local/bin/youtube-dl

If you need .tar.gz: sudo curl -s https://api.github.com/repos/ytdl-org/youtube-dl/releases/latest | grep 'browser_download_url.*tar.gz"' | cut -d : -f 2,3 | tr -d \" | xargs -n 1 sudo curl -o /usr/local/bin/youtube-dl -O -sSL

The first part generates the latest release link, like:
https://github.com/ytdl-org/youtube-dl/releases/download/2021.02.10/youtube-dl-2021.02.10.tar.gz and pipes it into the curl (sudo required to save to /usr/local/bin.

I can submit a PR to README.md if we want to add this here, though not sure how useful it might be given DMCA takedowns of this repo happen.

curl failed to verify the legitimacy of the server and therefore could not

In addition to the workaround on this issue, I created a tiny microservice for pointing the latest youtube-dl binary available at GitHub releases:

• for UNIX (Linux/Mac): https://youtube-dl-binary.vercel.app
• for Window: https://youtube-dl-binary.vercel.app?platform=win
