it's just so risky, last time i updated my S19 pro firmware, i couldnt access the HTML page for almost a week ,, it just kept on jaming on my ,, and then it came back on !!
Did you solve this problem? Or are you currently having this issue?
Sometimes this happens due to firmware corruption if you experience this again I suggest you revert it back to stock firmware and use the SD card flashing that you can find on Bitmain support
