Cannot open COM, access denied during fundamentals course

Hello,

I'm stuck in the nRF Connect SDK Fundamentals course on lesson 3, exercise 1. When opening the COM port to view the printk messages, I get an error when connecting to VCOM0.

Connection to VCOM1 works, but there I can't see any output.

I also tried the solution: fund_less3_exer1_solution, but the same error occurs there as well.

adding:
CONFIG_CONSOLE=y
CONFIG_UART_CONSOLE=y
to prj.conf also didn't solve the issue.

What else can I try?

I'm using the nRF9161 DK

Thanks!

Rene Fischer
