Cannot connect if behind a HTTP proxy

[esalagea]

The script works just fine if not behind a HTTP proxy. thanks a lot for this downloader, is the best I found for coursera.

If I run it behind my company's http proxy, I get:

./coursera-dl --debug -u userName -p pasword class-id

Here is the output

root[main] Downloading class: class-id
requests.packages.urllib3.connectionpool[_new_conn] Starting new HTTP connection (1): proxy.mycompany.com
requests.packages.urllib3.connectionpool[_make_request] "GET https://class.coursera.org/course-id HTTP/1.1" 200 None

We have seen this problem before and we never managed to get it to work :(
Can you set the HTTP_PROXY (and/or HTTPS_PROXY) environment variables and try again?

$ export HTTP_PROXY="http:https://proxy.mycompany.com"
$ export HTTPS_PROXY="https://proxy.mycompany.com"
$ ./coursera-dl --debug -u userName -p pasword class-id

If this works, we should add a proxy option to coursera-dl.

I tried it, same result. sorry :(

You shouldn't need to add the proxy option to the script, it handles the
enviroment varaibles just fine. Per application proxy rules are a pain to
maintain for users if they have to access multiple networks with different
proxy configurations. I am using coursera-dl through a corporate proxy
without any issues.

Are you able to get out of the corporate network using any other
commandline programs like curl or wget?

If you try to run 'wget http:https://google.com' do you run into the same issue?

Depending on your distro, your env variables may be different. Using all
caps for me doesn't work, I have to use lower case, it may be the same for
you. Here is how I have my proxies set up in my .bashrc:

export http_proxy=http:https://PROXY_URL:PORT
export https_proxy=$http_proxy

this is the output I get:

@esalagea did you try EmptyOne's suggestion?

[esalagea]

I'm sorry. Maybe there is something something tricky in my configuration.
wget works just fine (I tried it on a coursera https page).
Exporting lowercase http_proxy did not help. Same output.

For info, if using Windows you would need to use set.
eg:
set HTTP_PROXY=http:https://host:port
set HTTPS_PROXY=http:https://host:port
