ST-LINK V2 does not work

Hi!

I would like to ask for a little help. I have a LoraWan E5 wich I want to program with ST-Link V2, but as soon as I want to connect to it in the STM32CubeProgrammer I get the errors below. I also attached the pinout that I follow. I connect SWDIO, SWCLK, 5V and GND to the LoRa e5 mini. If I ping the lora with an AT command it responses on the serial monitor so the LoRa is ok. I updated the firmware wich was successful, also tried to set to reset mode and press the RST button while connecting but none of these are work. How would I be able to connect it?

So adding RST would be good.

Again, Have you contacted Seeed Studio for support? It's their board...
