I designed my board using the STM32L476RGT6. However, when using the ST-Link via SWD, I get the following message:

Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication.

I have checked all connections and voltages, and everything is correct, with the proper 3.3V values.

I am sending the schematic and a photo of the programmer.

Note: I did not solder the VCAP capacitors, and there is no voltage on these pins.
