something regarding keepalive time, nothing serious.

I have not been able to make the connection with this ONT and this is the beginning of this issue of why it does not connect.
I did the same as in the other one, delete the password in the ONT from the Request, reboot, delete from ACS but I still have a connection error

I think you may have to engage the CPE vendor for support on this.
