Hello,
it seems that the webinterface doesnt support mutliple connexion,
If I connect a first device (my laptop) works well, but as soon as make a second connexion with mz mobile device, the interface do not respond anymore, I have to restart QLC so I can connect again with one of them.
It is a bit annoying as usually I have my laptop standing next to the drum in my band to manage the show during live and when we do sound check or breaks,I can manage the scene from another place in the room.

So I was wondering if this is the default webserver behaviour by design to only handle one connection or if I have to configure my raspiOS to handle that

Thanks !

I have just ran QLC+ on a Linux laptop with web access actiaved (which is the closest setup to a RPi)
I connected:
- from Chrome on the same PC
- from my Android smartphone (via Wi-Fi)
- from an Android tablet (via Wi-Fi)

Everything was OK and actually working pretty good.
I can press buttons, move faders, change frame pages, etc and all three devices were perfectly in sync

I'll try with my RPi 5 when I have some more time

Hi, this might have been fixed by https://github.com/mcallegari/qlcplus/pull/1749. If you are willing to test, then try to grab a development build. See the download page, section "Development Builds" on how to obtain one.
