Cannot Access Web Gui, Alerts Come In

Since last Friday I am unable to access the web gui. Alerts are still coming in, but I cannot take action. Below is an error from the librenms.log. I’ve checked with my AD team and no changes were made to AD in the last few months. I’ve even tried resetting the service account password

Anything? This is still broken

May have figured this out, looks like an issue with Edge. It started working apparently a few days ago on other browsers. Maybe something with a daily?

We had a very similar issue recently. I was getting the “Whoops, looks like something went wrong” error on the Libre webUI, and was seeing an ldap “Unable to bind to server” error.
Root cause in our case was that someone overwrote /etc/ldap/ldap.conf on our Libre server which removed the following config that is required for our LDAP system:


Once I put that line back into ldap.conf it started working normally again.
