Assuming the connection is correct, I guess you didn't enable SWD.

If you didn't enable the SWD interface in the firmware, It will be disabled after booting, the programmer won't be able to connect unless you use nRST pin, or manually hold nRST low before clicking on Program, and then release.

The manual method requires some tries until getting the correct timming​
