<![CDATA[Error setting up XMLRPC]]>Hey all,

Getting a new alert when setting up XMLRPC below:

New alert found: Exception calling XMLRPC method host_firmware_version # Received non-200 HTTP Code: 301. Response body:<html>\x0d

Can ping between the devices on the SYNC interface so traffic is routing correctly, and the firewall rules are open for testing and I still get the above message when saving the setting.

Also the following:

/rc.filter_synchronize: The Netgate pfSense Plus software configuration version of the other member could not be determined. Skipping synchronization to avoid causing a problem!

Confirmed that both versions are on 21.02.2.
XG7100U models

Any help would be appreciated!

The error I'm getting says that the "software configuration version of the other member could not be determined." Would setting them both to use http/80 help in this case?

I'm not seeing an HTTP or HTTP setting in the System / High Availability Sync page.

I am still getting the same error when I enable HA sync. (Logs in reverse order, newest at the top).

Was a simple fix and must have missed it during the setup

Have a pair of SG-1100's, Sync interfaces are connected, can ping between them. FW rules passing all traffic on the Sync interfaces.

Enabled HA Sync on both, primary node has the XMLRPC settings.

System log on primary has some puzzling errors:
