no internet connection / tty connection

[TCH]

Hey,

i have a pi4b with a CNAT buster full image and 4 raspberrypi0's

i had a connection via ssh and via tty (minicom p1).

i installed the following:

docker on every pi

added all raspberry pi 0 to swarm with the raspberrypi 4 as master

after a while i cannot ssh into the pi's and minicom gives the following error:

minicom: cannot open /dev/ttypi1: No such file or directory

when i type ls /dev/ttypi*  the output is:

ls: cannot access '/dev/ttypi*': No such file or directory

does anyone have tips for me?

some info:

Hi, 

does anyone have tips for me?

Can you run the following and send the output to sup...@8086.net.uk with details of which images you're using please and I'll take a look.

uname -a ;cat /proc/device-tree/hat/* ; echo ; dmesg|grep "cdc\|usb" ; lsusb -t; sudo ifconfig -a ; sudo brctl show 

Thanks,

 Chris.
