Cpanel changed primary outgoing IPv4 and then it complains about license not valid

stAn

We are using Ubuntu 22.04 with latest cpanel and upon last night cpanel upgrade, it had changed order of IPs within output of "ip addr list" and thus the primary outgoing IP address had been changed. We cannot see the primary IP in "ip route" output either, this had worked till last night's cpanel upgrade. 

 

What are our options to resolve this issue ? we cannot afford a downtime in this time. We pay full dedicated license for cpanel and it's not acceptable that there is no way to contact support in this matter directly. 

 

Summary: 

1.we use one primary IPv4 address
2. we also have /29 subnet configured purely with cpanel 

3. we also have /64 subnet configured with cpanel which was unreliable - cpanel had been dropping IPv6 upon some ugprades

output of "ifconfig" correctly lists the primary IP as the first one registered to "enp1" while all other addresses are registered to "enp1:cpX". 

 

Thank you, 

Best Regards, Stan, in the name of a client - please ask for further information

    That sounds more like a Ubuntu update (that may have been applied via upcp).  What exactly do you mean by "changed order of IPs"?  The output of ip addr list would prob. be useful, just obscure the first couple of octets.

    it is definitely cpanel itself, not ubuntu

    "netplan apply" and restart all services on IPs on ubuntu fixes it, while "rebuild IP pool in whm" causes unpredicted results: 

    - some IPs are randomly missing

    - incorrect 176.Z.Y.220/29  and others in command outputs (our IP range is purely - 176.Z.Y.216/29 ) 

     

    output after "netplan apply" and issues after "rebuild IP pool" : 

    this resets the config to the config file:

    AFTER RESTART OF WHM + REBUILD OF IP POOLS all IPs it seems to be fixed for now... we'll see what next cpanel upgrade brings.. 

     

    If you could at least suggest an Operating System that got at least 4 years to-EOL support and is compatible with cpanel and hetzner. (RT clones 9 are not). We chose Ubuntu for largest LTS support but it seems cpanel had changed it's mind of stopping support of Ubuntu 22.04 when they release Ubuntu 24.04 which makes it just 1.5 year of real support...  I a very disapointed by this.
