Issue: Name huawei.com (SOA) not subdomain of zone cloud.huawei.com -- invalid response

[Jesus Cea]

I am getting errors "Name huawei.com (SOA) not subdomain of zone 
cloud.huawei.com". The problem raises when requesting AAAA on 
oauth-login.cloud.huawei.com . The problem was described in the mailing 
list:

https://lists.isc.org/pipermail/bind-users/2021-January/104064.html

BIND is replying with a SERVFAIL. This is correct and appropriate. 
Nevertheless resolvers like 8.8.8.8, 1.1.1.1, 9.9.9.9 and many (most) 
other are not doing that SOA verification, so for users we are the 
guilty, not Huawey, because "using Google it works!". In fact, we have a 
big customer phone app failing because of this (yes, this seems to be a 
bug with that app but, again, "with google it works!").

What can we do? Is possible to disable that check in bind?

We are using 9.16. We could upgrade to 9.18, if needed.

Thanks.
