GitHub user Kami opened a pull request:
https://github.com/apache/libcloud/pull/682
Throw a more friendly error message if establishing SSL / TLS connection
fails
With this change we now throw a more user-friendly error message in case
establishing SSL / TLS connection fails.
New error message:
```python
File "/home/kami/w/lc/libcloud/libcloud/httplib_ssl.py", line 312, in
connect
raise new_e
socket.error: Failed to establish SSL / TLS connection ([Errno 104]
Connection reset by peer). It is possible that the server doesn't support
requested SSL / TLS version (TLS v1.0).
For information on how to work around this issue, please see
https://libcloud.readthedocs.org/en/latest/other/ssl-certificate-validation.html#changing-used-ssl-tls-version
