I hope, that I can get a solution of this little problem. I am working with the RPI for at least 4 years.
Yesterday I got my new Pi4. I created a new Raspbian Boot medium with the latest Buster Image. Also put a "ssh" file in the boot partition.
My Pi seems to boot and got an IP from my mikrotik router.
The Prob: I get an error: Connection refused and I am not able to access the Pi. Sadly I have no HDMI Cable due to the new Ports.
I never ever needed a cable, because all my Pi Projects and all my RPI3 worked that way of headless Installation.
After shutting down the Pi - the "ssh"-File has been deleted... Very strange because I thought that happens, after a SSH Connection has been succesfully established.
Does anybody has a Solutution?
Thank you in Advance.
