Our site (edit server) requires https to function, which means that siteUrl and uiUrl is explicitly set to https, and also corresponding authentication section in web.config.
We keep getting scheduler errors in the log, and when running [the scheduler] in debug mode we get the following indication that it cannot contact the site correctly:
#ERR# Failed to start site https://site/, error "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
#INF# [_LM_W3SVC_3_ROOT] Failed calling site (Server encountered an internal error. For more information, turn off customErrors in the server's .config file.)
(And no, the real URL is not "site" :-))
How can we make the scheduler work with a secure site?
