But in terms of the network, I must be able to reach the host because the host has a network card installed in it which is located in that network. So it should be on the same network. And just to be sure, I also checked the firewall and no packets are being sent through it.
I can also contact the API with the admin.conf file from another host in another network and that works…
I also tried to run it once with one of the masternodes because I have a HA installation which has a virtual IP from a LoadBalancer in front of it, but there I have exactly the same problem. So the load balancer in front of it cannot be the problem.
The master nodes are also all up and ready.
