I should add that I reloaded Volumio yesterday as there was a network issue I couldn’t resolve. I put it on a 64Gb sd just incase there was too much data but timeout issue still there.
I reckon that might be a hardware issue, for the last few versions of Volumio mine has run very reliably 24/7.
I never turn it off, and it’s been available via SMB shares, web browser and app without a hitch for months.
Mine’s on an R Pi 3B+.
Sorry to revive this thread, but I have the exact same issue. What did you do with the router to solve the problem? I suspect my router might be to blame, but I don’t know where to begin.
