Are you sure the guac client is actually connecting to xf86-video-guac? I
don't see any messages in the X.Org logs which indicate a connection

on when the connection attempt was made, are you sure the X.Org server was
running at the time?

Any idea what that "502 Proxy Error ... POST /service/logEvent/chronology"
error is about?
