Laravel framework can give a 419 if the CSRF cookie can not be set/read.
Please check if your browser blocks that and if the FQDN you use to reach LibreNMS does match the host-configuration in Libre.

Thank you, Chris, for your response! I really appreciate it.

I’m still learning the more advanced areas of Linux. I checked the FQDN in /opt/librenms/config.php and $config[‘base_url’ is commented out.

I also checked the FQDN in /etc/nginx/sites-enabled/librenms.vhost and the server_name is set to librenms.domain.com; domain, of course, being my domain.

Would you mind letting me know how to check to see if the CSRF cookie is set and can be read? I greatly appreciate it!

Please check if the file “.env” in the librenms root-folder contains a line:

SESSION_SECURE_COOKIE=true

Then try to clear the session cache by runing command:

php artisan cache:clear

I checked SESSION_SECURE_COOKIE and it is set to true. I also ran php artisan cache:clear and rebooted, however still have the issue. :frowning:

Any other ideas?
