run "ip route show" and see what position in the string the gateway address is for usb0. Probably need to change line 71 to :

tunnelInterfaceGW=$(ip r | grep 'default.*'${tunnelInterface} | awk '{print $9}') specifically for usb0.

You can also add a check like this:

tunnelInterfaceGW=""
# let's read out the default gateway from the main table
if [ "$tunnelInterface" = "qmimux0" ] || [ "$tunnelInterface" = "qmimux1" ] || [ "$tunnelInterface" = "ubs0" ] ;
then
    tunnelInterfaceGW=$(ip r | grep 'default.*'${tunnelInterface} | awk '{print $9}')
else
    tunnelInterfaceGW=$(ip r | grep 'default.*'${tunnelInterface} | awk '{print $3}')
fi

(For simcard interfaces such as qmimux0 / qmimux1 the gateway address is also at position 9 in the output string)

Unplug the internet connections from the connector and reconnect them.
It worked for me.
