simulink: When i connect element, it shows red dashed line and red circle

i want to connect the inductor below but it keeps having this problem

can someone help me please?

Darn, I thought I saw another question on this same topic today, but without a diagram. I cannot find it now, though.

Meanwhile, perhaps one of these two is relevant:

Answer 1

As explained in the links that Walter posted, the rest of your blocks appear to be Simulink/SimPowerSystems blocks which do not mix with the Inductor which is from the Simscape (physical modeling) domain. See Guy's anwer here for more information.
