This means you forgot to add -flags +global_header 
which is mentioned in the documentation of the tee 

As said, please don't use -deinterlace, it may have 
funny effects particularly with specific muxers like 
tee. Explicitely specify a deinterlacing filter instead.

The tee muxer never prints more, I would assume it is sending 
the streams to two rtmp connections. Is it not working with 
the global_header flag added?
