Hello Kwiatjk,

Can you let us know a little more about your configuration? Could you let me know which address family you have configured for your server? Are you using IPv4 (e.g., '192.168.1.1') or IPv6 (e.g., '2001:0db8:85a3:0000:0000:8a2e:0370:7334') addresses?

Are you working in a specific environment like a local development setup, a virtual machine, a containerized environment like Docker, or a cloud platform? Each of these environments can have unique network configurations and limitations.

I have this issue as well. It's RHEL 8.8 on an IPv4 only system. Physical workstation. To make it work I added ip = 0.0.0.0 to the ncpa.cfg file, but was working fine without that with ncpa 2.

I added ip = 0.0.0.0 to the ncpa.cfg file, not working for me

@Kwiatjk What do you have set in your [listener] section of your ncpa.cfg? The ip and port set in the listener section of the configuration is where NCPA sets the gevent's WSGIServer address and are likely where your issues are initializing from. If not set in the configuration file, the address will default to :: unless you're on Windows in which case it would be 0.0.0.0 and the port will set to 5693.

I added ip = 0.0.0.0 to the ncpa.cfg file,

not working for me

Did you add it under the [listener] section where there is an ip = and port = commented out?

[ne-bbahn]

Someone found the issue. It seems that when ipv6 is disabled, NCPA won't start. I will try to get this solved for 3.0.1

[ne-bbahn]

Fix will be in 3.0.1
