no option to bypass ssl certificate : "certificate verify failed"

I'm using planemo to test some workflow on a galaxy instance.
I have no problems on a certified site (SSL certificate) but when I'm trying on a self-signed certified url, I'm having this error:
`requests.exceptions.SSLError: HTTPSConnectionPool(host='usegalaxy.ifb.local', port=443): Max retries exceeded with url: /api/workflows/upload?key=81c3b3... (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)'),))`

Which is fine since it is not a valid SSL certificate.
My question is: What can I do to bypass this SSL certificate check ?

I added my self-signed SSL certificate locally with `dpkg-reconfigure ca-certificates` but still got the same error.

Is there something I can do to use planemo on an instance with a self-signed SSL certificate ?
