I'm pretty new to system administration, and I was wondering if I could get some support. Recently, I updated the OS version of my virtual machines from centOS 7.4 to centOS 7.5. After the update, I rebooted the servers. This is where my problem begins. I currently have an access management setup that uses 4 virtual machines: one that hosts the admin console & identity server, one that hosts the analytics server, and one that hosts an eDirectory via iManager. This setup was perfectly fine before the reboot, which leads me to believe there was some some sort of unsaved configuration. However, now my identity server which is running on a local VM ending in 108 is not communicating with my eDirectory running on a local VM ending in 106. According to the server health details the use store replica is not responding. "Ensure that all replicas of this user store are operating correctly". I'm trying to connect to the replica using SSL on port 636. The exact validation status is "Connection refused (Connection refused)". When I do a netstat I see that my identity server is listening for port 636 but nothing is on it. I'm not sure what happened, as I mentioned before this was all working before the updates. Please let me know if anyone can provide some support (possibly live). Thanks!
