Error Can't open serial uploading Mini Web Server


#1

Hi, I just virtualized my NodeMCU v2 (Windows 10) and tried to uplink the script Mini Web Server, but I’m getting the error “[error] Can’t open serial: COM11”

This is the result of the compilation:
[info] ########## STEP 4 - generate binary
[info] Resource table at 1276 0x4fc
[info] Saving to C:\Users\aom_o\zerynth2\tmp\zstudio.vbo
[info] Compilation Ok

And part of the uplink process:

[error] Can’t open serial: COM11

And the message below appears in the console:

Lost connection!

Am I doing something wrong?

Thanks a lot

There seems to be a problem with the serial communication with the board.
can you open the COM port through any serial terminal application?
