Description Of Issue
My Samsung phone can’t find the Roon Server unless I start the Roon App on my PC first. The Roon App and Roon Server are on the same PC. Also it takes ~15 seconds for the Roon App to start on the PC. Once the PC Roon App has started Roon seems to work OK and plays music and can be found by my phone. I’ve also noticed that roughly every 10 seconds the Roon Server is generating a new log file with the error ‘Object reference not set to an instance of an object’ - see log extract below.
Although I’ve seen similar errors reported elsewhere, I couldn’t find a fix. Which is why I am reposting.
