Hi, I had an issue with my Wireless network and was required to reconfigure my network. I set it up as before and since I’ve been unable to stream to my Airport Express. I’ve just upgraded it to the latest firmware at the same time, and tried renaming the Airplay endpoint in case it was a conflict…

Airport Express has stopped working via Roon

It is the case as a simple search of the forum confirms, I would suggest rolling your fw back.
