CentOS

I Have the same problem with CentOS 7 since the system has been updated. Concretely how did you solve your problem, since I can't re-install the system completely, did you proceed with an update or else ? I don't really remember what i did exactly :geek: But I thing it was "yum install kernel" and ...

Thank you all for your answers.
The problem was the OVH kernel.
With the CentOS kernel 3.10.0-1062.1.1.el7.x86_64, everything works well.

Yes but this module was not needed by firewalld with Centos 7.6? Is it a new feature?
Would the original CentOS kernel be OK?

Thanks.

Server 1:
4.9.185-xxxx-std-ipv6-64

Server 2:
4.19.62-mod-std-ipv6-64-rescue

they are ovh servers with the kernels provided by them.

Thanks.
