Search logs appears to hang

[Netcontact]

Running Nagios Log Server 2.1.13 on RHEL 7.9, cluster of 3 nodes. All cluster health status shows green, but when attempting to search logs, the status circle just spins and spins with no results. All nodes rebooted to no avail. Indices older than 30 days are being auto-deleted as expected. What else should I look at to get the search function to work again?

Since there are multiple methods of searching logs, could you be more specific as to how you're doing this? i.e., are you putting in a query string in the dashboard?

It will be helpful to have some information from the web server logs on your system. Are there any 500 errors showing up in /var/log/php-fpm/www-error.log while you're searching?
