Multiple Radius Servers - unable to connect using OpenVPN

[SvenVW]

Hi,

I'm experiencing a problem when we set up 2 RADIUS servers.
At the moment we are migrating to a new domain, so we have a Radius Server in both domains.

Both servers are selected in the OpenVPN server configuration:

And testing credentials using "Diagnostics -> Authentication" works with credentials in both domains.

But when trying to log in in OpenVPN GUI I get "wrong username or password":

Removing a server solves the problem:

Is there a way (or a setting I'm missing) to use 2 RADIUS servers?

pfSense version "2.4.4-RELEASE-p1"

Do both servers work in Diagnostics > Authentication?

[SvenVW]

Yes, both work

First server:

Second server:

The login problems only occur when both authentication servers are selected.
When only one is selected, I'm able to use OpenVPN in the selected domain.

Best regards,

Sven

Anyone else has an idea?
