Make sure you entered your Bitcoin address correctly and that it is the same address as your looking for stats for. S9's have been known to be hacked and pointed elsewhere.
My setup is currently sidehack's R606's. So I see the full CGMiner stats on my Pi 4. So I'm accustomed to seeing more detailed info in real time. I don't know what type of info an S9 shows you.
