Hi RR1

Thank you for your help. Its working now. I also did the below commands

cp /etc/php/8.1/fpm/pool.d/www.conf /etc/php/8.1/fpm/pool.d/librenms.conf
vi /etc/php/8.1/fpm/pool.d/librenms.conf

Change [www] to [librenms]:

[librenms]

ln -s /opt/librenms/lnms /usr/bin/lnms
cp /opt/librenms/misc/lnms-completion.bash /etc/bash_completion.d/

None of the suggestion made here has helped resolving this issue. I guess no one has the solution for this.
