Hi,
the Pi is a 3 Model B. The output of the PSU says 5.1V and 2.5A. Is that enough? Also I don't have any further storage connected. For sharing I'm using some space of the 15G card where the OS is installed on.

The only additional piece of hardware is a bluetooth keyboard/mouse device, which is connected via usb dongle. On the software side I only installed a samba server and opened the related ports with a firewall command.

No ping is possible, also there is no HDMI signal anymore - the only thing I can do is restart it. I'm keeping the software up to date, but that doesn't solve the problem.

There's no known issues I've seen running it from a Server PoV but
there's some common issues. Do you have the storage for the share on a
USB HDD or is it just sharing space on the SD card? What model of RPi
is it and what is the amp rating on the power supply. The most common
issue is caused by a PSU that's not strong enough.
