Hi,
it compiles wonderful now with the updated libraries, thanks for the fast help 
But i ran into another problem while trying to upload via ota:
i added the line upload_port = 192.168.0.104
in my platformio.ini (ip is correct)
and it seems like he tries to open a file/tty named ‘192.168.0.104’ ?
Here is the error msg:
serial.serialutil.SerialException: [Errno 2] could not open port 192.168.0.104: [Errno 2] No such file or directory: ‘192.168.0.104’
*** [upload] Error 1
and here is the complete ini, hope it helps:
[env:hornbill32dev]
platform = espressif32
board = hornbill32dev
framework = arduino
upload_port = 192.168.0.104
It works on arduino IDE, did i miss to add some configuration somewhere?
Greetings
