Service not available 503 with lagg0 and lagg1

[gondim]

I have an HP Proliant DL-360G5 with four network interfaces: bce0, bce1, and bce2 bce3.

I created two interfaces: lagg0 and lagg1.

lagg0: bce1, bce3
lagg1: bce0, bce2

WAN -> lagg0
LAN -> lagg1

I'm accessing the internet normally but access to the interface of pfsense is extremely slow and sometimes displays the error: service not available 503
