Description of your issue:

I'm inside a company network that uses a proxy. But I'm not quite sure, why the download isn't working. I can download youtube videos using other graphical downloaders like Free Download Manager. Also, I can view this video in any browser without having to find a way around the proxy.
I'm not sure if the proxy is hindering youtube-dl to download the webpage to get all necessary information out of it, or maybe I just entered the proxy wrong?

I'd really appreciate your help.
Thank you in advance and kind regards,
Kevin van Thiel

p.S.: Attached you can find Screenshots of the Configuration File and the cmd output:

[dstftw]

Most likely it's not a socks5 proxy.

[GecoMynx]

Most likely it's not a socks5 proxy.

Okay, what do I have to enter for the Proxy to work then?
--proxy http://proxyde.hoist.de:8881/ ?
or maybe
--proxy https://proxyde.hoist.de:8881/ ?
Or somehow both of that? Can't find anything according to the syntax in the manual. :/
Maybe it's just
--proxy proxyde.hoist.de:8881 ?

However, it doesn't seem to matter what I'm entering there.
I'm still getting error messages:

The Error-Message looks always the same, whatever I'm trying to use as a proxy.
Is it because the Proxy is blocking it? I can't read the verbose log, so it would be great to know why it's erroring out...

[GecoMynx]

Our Proxy is using authentication for the Users.
Is it possible that I have to enter my credentials at some point?
But how tho?

[GecoMynx]

Okay, you can close this case now, I found the issue.
I just had to explicitly NOT use the Proxy by entering the following line to the config-file:
--proxy ""
