Power net portal is a special schematic object used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design. Power nets of the same designator automatically connect throughout your design #portal #power

This forms a closed loop, but usually, LEDs are either connected to a power source and ground or in a controlled manner via a driver circuit.
Forward Voltage:
Since each LED has a forward voltage of 1.7V, in total the series connection would not light up correctly without a proper power source and current limiting resistor.
If the power source is provided directly to the series-connected LEDs, the total forward voltage drop will be $3 \times 1.7V = 5.1V$.
Current Limiting:
No resistors are mentioned, which are typically needed to limit the current through the LEDs to prevent them from burning out.
Recommendations
Power Supply & Ground: Ensure there's a proper connection to the power supply and ground.
Current Limiting Resistor: Add a resistor in series with the LEDs to limit the current to a safe level.
Check for Loop: Ensure there's no unnecessary loop, your LEDs should typically be in series with a resistor to ground or to the supply voltage.
Would you like help to design a correct schematic for this using a specific power supply voltage?
The way you have specified the nets suggests that all three LEDs are interconnected in a cycle with every anode (A) and cathode (K) connected together. The issue here is that a net, typically, should not connect both anode and cathode of the same LED to the same net. This will result in an electrical short.
The connections as mentioned will form the following net:
Typically, LEDs are either connected in series or parallel. In series connection, you would connect the anode of one LED to the cathode of the next LED and so forth.
In this case, you'd need to verify if the total forward voltage of LEDs in series can be satisfied by your power source.
Parallel Configuration:
In a parallel connection, the anodes of all LEDs would be connected to the positive power rail and cathodes to the ground.
Suggested Correct Net Connections
I assume from the provided information that you might want to connect the LEDs properly in a logical manner. Based on a reasonable guess, assuming serial or parallel based on your power configuration, here are two corrected net configurations:
LED1:A, LED2:A, LED3:A (all connected together to the positive rail)
Net2 connects LED1:K to Ground, LED2:K to Ground, LED3:K to Ground
Summary
Serial Configuration:
LED1:A to Power Source
Connect LED1:K to LED2:A
Connect LED2:K to LED3:A
LED3:K to Ground
Parallel Configuration:
LED1:A, LED2:A, LED3:A connected to Power Source
LED1:K, LED2:K, LED3:K connected to Ground
Make sure to confirm the supply voltage and adjust the series resistor if using a different voltage source to ensure safe operation of LEDs.
