Web Practices Do Not Count?
Does desktop practices count? I practiced yesterday via "Strengthen" button and my streak is still zero.
It depends what your goal is set to. If you do less than your goal, then your streak will be lost.
Also, get a streak freeze, and check regularly that it is enabled.
Your extended user profile shows your last activity was on the 10th (2 sessions, 19 & 28XP), so I can only conclude your practice yesterday somehow wasn't "submitted". Maybe you didn't press "Continue" after the last question?!? I assume you have working internet on your desktop? Also, you can check whether you have reached your daily goal by making sure there's a green checkmark on the flame in the top bar.
