CARP backup shows master

sforman

I recently added another Netgate 2440 and wanted to setup CARP on it for failover. To the best of my knowledge, I have everything configured correctly but CARP is showing MASTER on both nodes.

The error I'm getting in the system log on my primary node is as follows:
php-fpm[76972]: /rc.filter_synchronize: An error code was received while attempting XMLRPC sync with username admin http://192.168.4.2:80 - Code 5: Didn't receive 200 OK from remote server. (HTTP/1.0 301 Moved Permanently)

From Status (CARP failover on primary)
LAN@1 10.111.130.143 master MASTER

(secondary)
LAN@1 10.111.130.144 master MASTER

192.168.4.1 is the SYNC interface on the primary node
192.168.4.2 is the SYNC on the secondary and they are directly connected through a cable on igb2

I have a firewall rule on each server allowing all traffic from the Sync Net everywhere.

In System/High Avail Sync, Syncrhonize States is set to 192.168.4.2 on the primary node.

I'm running version 2.2.6 and have auto-submitted a crash report for the bug when prompted.

What is "moved permanently"?
Is there a workaround for this bug or another configuration I could try? Any suggestions would be greatly appreciated. Thanks in advance.

Answering my own question, the "moved permanently" error was caused by protocol mismatches. I had HTTP enabled on my primary and HTTPS on the backup.
From:
https://doc.pfsense.org/index.php/Configuring_pfSense_Hardware_Redundancy_%28CARP%29

Before proceeding, set the same admin user password and webConfigurator protocol (e.g. HTTPS) on each cluster node.

This protocol is set at: System/Advanced/Admin Access/Protocol
