No /play or /loop on "Ctrl" for iPad

[LexiMaker]

Hey, first of all thanks for the code !

I changed the Port to 56000 to match the "ctrl" app for iPad. Qlab is just working fine.
Via "ctrl" from ON LX (https://onlx.ltd/ctrl-for-ipad) I can /pause /stop and /cmd but when I try to start a video with /loop or /play the video wich was playing back (startet on Qlab) stops but the new video isn't starting.

do you have any suggestions where to look at, seems to be a path problem...

Thanks,
Lexi
