Ok so ive waited over 30m, and it works good, so probably it breaks if its shut down for whole night/day, when the day actually changes, it doesnt matter which channel i use, its always the same, i have 3 boxes, every box is on a different channel and one is on a different satelite, and the issue is exactly the same on all of them, both from ntp (wifi and ethernet) and transponder time, so ill post more info tomorrow, when its desynced again i guess
