Rolling back to 5.5.1.7 will fix it. 14 of my cameras are Reolinks and 5.5.1.9 results in the 5 Reolinks all getting no signal and the BI UI freezing over and over again. Those 5 camera failures appear to be tied to one specific Reolink camera that when disabled the other 4 work fine with 5.5.1.9. Rolling back to 5.5.1.7 and all 5 cameras are fine. I've repeated this 3 times and it's broken every time I re-instlal 5.5.1.9. Please no comments about how crappy Reolink is. I already know.
