Midori browser doesn't start a second time in script

Question

Hello I have an apache webserver running on my Windows 10 PC with xampp and a RaspberryPi to connect to it with a script. The script checks if the webserver is available on specific port and if ist available start the browser and close it if the server is not available anymore. Here's my Script:

#!/bin/bash

### BEGIN INIT INFO
# Provides:          browerstartup.sh
# Required-Start:    
# Required-Stop:     
# Should-Start:      
# Should-Stop:       
# X-Start-Before:    
# X-Stop-After:      
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# X-Interactive:     
# Short-Description: If connection available, connecT!
# Description:       If connection is available on port 80: Then connect.
### END INIT INFO

server="192.168.16.74"
sleep=10

while [ true ] ; do
echo "Script start" >> /home/pi/browserlog
 midori=$(pgrep "midori")
 nc -w 5 -z $server 80 >/dev/null 2>&1
 if [ $? -ne 0 ] ; then
  echo "Server isnt running!" >> /home/pi/browserlog
  if [ $midori ] ; then
   echo "Midori is still running but server is offline: Killing midori"
   kill $midori
  fi
 else
  echo "Server is running!" >> /home/pi/browserlog
  if ! [ $midori ] ; then
   echo "Starting midori" >> /home/pi/browserlog
   midori -e Fullscreen -a http://$server/Website/t1&
  fi 
 fi
echo "Sleep $sleep" >> /home/pi/browserlog
 sleep $sleep
done

The first time I start the webserver it connects and starts midori and if I stop the webserver it closes midori. But if I start the webserver again it doesnt start midori any more and I have no idea why...

Here is my browserlog file:

Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start

Starting midori

Starting midori
Sleep 10
Script start

Starting midori
Sleep 10

Here I stopped the script manually!
