Following the instruction for Odoo's oauth provider and developer google project  authentication settings (using https://mydomain/auth_oauth/signin" )  I keep getting the problem when using https:// as default protocol.

The "request.httprequest.url_root" from controllers/main.py (line 58 and 75) sending out http:// as default protocol.   So, when Iogin with Google account. I always got  "Error: redirect_uri_mismatch" error.

So, what should be done? I try to modified the main.py to use "web.base.url" but keep getting the following error:

File "/opt/odoo/addons/bus/bus.py", line 188, in poll

raise Exception("bus.Bus unavailable")"

And the system was lock at 500 error.

So, anyone can share the possible solution will be appreciated.
