I cannot connect to Octopi, I know the IP number and can connect to the Raspberry Pi. Octopi tries to connect and immediately it disconnects
What did you already try to solve it?

Have you tried running in safe mode?
No how do I run in safe mode (I'm a newbie)

Systeminfo Bundle
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
Changing monitoring state from "Offline" to "Opening serial connection"
Connecting to port /dev/ttyS0, baudrate 115200
Changing monitoring state from "Opening serial connection" to "Error"
Changing monitoring state from "Error" to "Offline after error"
Unexpected error while connecting to serial port /dev/ttyS0, baudrate 115200 from hook default: SerialException: '[Errno 13] could not open port /dev/ttyS0: [Errno 13] Permission denied: '/dev/ttyS0'' @ comm.py:_open_serial:3775
Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
from the error message it may well be that the user you run octoprint as is not in the groups tty and dialout. Assuming it is pi you would do that like:
sudo usermod -a -G tty pi
sudo usermod -a -G dialout pi
You try to connect OctoPrint to a printer with lan/wlan port?
Or you have trouble to connect from your Browser to OctoPrint?
Or you have trouble to connect to a printer with USB port?
It would be helpful to tell us what printer you have.
That won't do.
That template you get when opening a thread on Get Help is meant to structure your response, it's a task list. People can not magically scan your system and it's history, you need to supply all the details so there's a chance other readers get an idea what goes off on your side.
You chose to ignore that. This is completly fine but limits the possible response.
You're left with the alternative approach: search the treasures of info stored in this forum.
