Cannot set certain FQDN on WAX630

I am trying to set FQDN on WAX630, but it doesn't allow FQDN like xxx.yyy.group. It is a legit domain name. I also tried xxx.yyy.net, and it works. The error I saw is: Invalid FQDN, please check...

Does xxx.yyy.group. resolve to the IP address of the WAX630?

"When connecting to a host (using an SSH client, for example), you must specify the FQDN. The DNS server then resolves the hostname to its IP address by looking at its DNS table. The host is contacted and you receive a login prompt."

Now you might dispute that certain DNS configs like split-horizon or internally used zones might not have not be resolvable by the DNS configured on the internal or management systems of your organization. However, checking if there is an A record for the FQDN (in fact the fully qualified host name) is the only option the AP can test - before it might no longer allow the admin access to http/https/ssh. Once configured, the AP does no longer allow http/https/ssh if not explicitly called by this name. Calling the AP using another URL, FQDN or the plain IP wont give access.

And I agree, the "(i)" hint isn't very clear about that.

Yes. xxx.yyy.group resolves to the AP's IP.

Just for my curiosity - also from the DNS IPs configured on the AP?

Strange the error message "Invalid FQDN, please check the syntax / ensure the domain name is registered for IP address" does state something different.

RaghuHR can you please check if the WAXxxx might not allow all valid TLDs, and then return a wrong error message?

  Yes. The DNS used by the AP has the same domain name to the AP IP entry.

    Hi page-faults
    
    We have made the restrictions to allow the following standards
    
    Original Top Level Domains - (.com, .net, .org, .edu, .int, .gov etc)
    
    Infrastructural Top Level Domains - (.arpa)
    
    Country code Top Level Domains - (.in, .us, .uk etc)
    
    We will allow .cancerresearch in our next release. Stay tuned. I guess you are not using Insight to manage WAX630 and it is in standalone mode only?
    
    Thanks,
