Browser refuse to connect to WebSocket when using insecure Galene behind a reverse proxy

[erdnaxe]

When running Galène in -insecure mode, groupStatus.endpoint will start with ws://.

This is problematic when using a HTTPS reverse proxy pointing to a insecure (HTTP) Galene as the browser will refuse to connect to ws:// from a https:// website.

A dirty fix could be:

+++ b/static/galene.js

This should be handled automatically if you set proxyURL in the config file. Can you confirm that proxyURL is set to an HTTPS address? Please see the code at https://github.com/jech/galene/blob/master/group/group.go#L1256

Please reopen if setting proxyURL doesn't fix the issue.
