I have installed a clustered Graylog Server. When I navigate to system/nodes , I encounter the error “Journal metrics unavailable,” specifically on the host that is connected via VPN(IPSec)
graylog log:

192.168.60.81(graylog01kar) and 192.168.62.115(graylog03kar) are on different VLANs, but they are in the same location. They can see each other, but they cannot see 192.168.25.81(graylog01ten) specifically. 192.168.25.81 is in another location connected via site-to-site VPN (IPSec) and there are no issues; all metrics are visible.
