I have the same problem after fresh installation, with some mysterious issues
- Access to Nethserver-GUI from the well used interface enp3s0 (used for installing, upgrading Centos, upgrading to kernel 5.x, Nethserver-installation) fails after NethServer installation.
- I tried to switch to the second interface enp2s0 - that was down. I activated it inside etc/sysconfig/network-scripts/ifcfg-enp2s0 an after rebooting this port is also active
- Access to the NethServer-GUI is still impossible
than is started the service
What is happened with the fresh installation? How could I fix this misbehavior?
