Hello all. I have Praxis works 110 bcd 52/36 10/11sp Cold Forged chainrings with a Shimano di2 ultegra shifting.
All the time when i am on the inner ring( whitout shifting) at a steep road and standing on my pedals my chain fell off to the frame site.
What can be the problem? The chainrings are mounted with the sign face the frame toward the frame.
Can someone help me with this problem?

Not enough chain tension?

Does it happen without pedaling?
