Infrastructure

right now, trying to login to ask via google fails because

The redirect URI in the request, https://ask.libreoffice.org/en/account/signin/complete-oauth2/, does not match the ones authorized for the OAuth client.

trying to migitate that one, I created corresponding API credentials in TDF's google account and replaced the client-ID/secret in askbot configuration for English project - while this doesn't complain about the redirect URL and shows the google login form, after entering the credentials askbot shows:

Internal server error
system error log is recorded, error will be fixed as soon as possible
please report the error to the site administrators

But I don't find anything in nginx logs or uwsgi logs - where to look for that/where's the issue?
