[Req#aa/MetadataAgentManager/getAgent] Unable to find metadata agent provider for identifier ‘https’

When I have trailers enabled to play before a movie, almost every time all I get is an error message that the transcoder could not be started. And then I have these messages in my log too.

Same here after I turned off all trailers all the movies started working again. Not sure if this was an issue after an update or not. It just started in Jan so could be new update.
