External File monitor failing

We migrated to version 11.6 and I'm having issues with an external monitor failing my pool nodes.

!/bin/sh remove IPv6/IPv4 compatibility prefix (LTM passes addresses in IPv6 format)

IP=

echo ${1} | sed 's/::ffff://'

IP=${1}

PORT=${2} PIDFILE="/var/run/

basename ${0}
.${IP}_${PORT}.pid"

kill of the last instance of this monitor if hung and log current pid

if [ -f $PIDFILE ] then kill -9 

cat $PIDFILE
> /dev/null 2>&1 fi echo "$$" > $PIDFILE

send request & check for expected response

curl -L --ntlm -k -v --user 'svc-dca-emea-f5monitor-gsps@ct.abcxyz.net:passw0rd' http://${IP}:${PORT}/_layouts/AccessDenied.aspx -H "Host: collab001-wfc.sp.abcxyz.net" | grep -i "Denied" 2>&1 > /dev/null

mark node UP if expected response was received

if [ $? -eq 0 ] then echo "UP" fi rm -f $PIDFILE exit

anyone have a better understanding of cURL that can help with my troubleshooting efforts?

    You might want to try sshing to the F5 and running the curl command but putting the pool member ip and port in instead of the variables like: 

    curl -L --ntlm -k -v --user 'svc-dca-emea-f5monitor-gsps@ct.abcxyz.net:passw0rd' http://10.0.0.1:80/_layouts/AccessDenied.aspx -H "Host: collab001-wfc.sp.abcxyz.net"

    then looking for "Denied" using any case.
