Domain Authentication Error

I have installed and configured the ipa-server and in my machine I'm running fedora workstation 30. After installing the ipa-client on my machine and well configure it I can not authenticate myself with the credentials that I have on the domain server. as you can see in the attached images, when allocating the machine in the domain gave an error like: 'failed to update dns records missing a reverse record(s) for address(es) could not update dns sshfp records' (please consult the attachments for better understandig) I've removed the machine and re-allocated it in the domain and the problem persists, tried other machines that gave the same error but after upgrading three times I was able to authenticate. but in this my machine in question the authentication problem persists. but only in the password, because the user name it recognizes immediately. -solutions already applied: 1-constant updating of the system; 2-reinstallation and reconfiguration of the machine; 3-reboot the computer countless times. I hope someone here can help me, first to better understand this type of error, which causes and also to solve the same urgently, I have to deliver some work soon.
