Pixel 6, Android 12, SS7 Pro 220.127.116.11
Stellarmate 1.7.1 (KStars 3.5.9, INDI 1.9.6)
"Connected to INDI Connection server but could not communicate. Please check your server setup."
No logs available, even with scope logging turned on.
Clearly SS7 is doing something wrong because telescope.touch is able to connect, KStars is able to connect. I'm VNC'd into my stelllarmate looking at INDI running right now.
