hotspot - full override; rule not working

Hello,
Just wondering if someone could help me understand why the following rule isn’t working.
Background: I’ve setup netwatch to ping the radius server, however sometimes the server host has issues so I’ve created a rule in the event of the route going up/down.

/tool netwatch
add comment="VPN Route" down-script=\
    "ip hotspot walled ip add action=accept server=hotspot1 comment=override" \
    host=IPADDRESS interval=5s timeout=10s up-script=\
    "ip hotspot walled ip remove [find comment=override]"
add comment="Watch Radius for link (hotspot override)" down-script="ip hotspot w\
    alled ip add action=accept server=hotspot1 comment=override\r\
    \n" host= IPADDRESS interval=30s timeout=10s up-script=\
    "ip hotspot walled ip remove [find comment=override]\r\
    \n"

However the function now longer allows for the override of hotspot logins. I assume this has occurred at some point because of a change in the ROS software update?
Can anyone suggest how to fix this issue.

Thanks
