If the Whitelabel - Host Mapping error is being triggered, the custom subdomain preferences cannot be saved due to any of the possible cases:
your subdomain was properly configured, but not yet propagated. Depending on the domain hosting provider, propagation time can vary
Nameserver changes can typically take 0 to 24 hours to take effect, but they are known to take as long as 48 hours to go into full effect.
If the Whitelabel - Host mapping has been enabled for [placeholder].awrcloud.com, a new subdomain is required, one which has the required CNAME: app.advancedwebranking.com.
The AWR Hostmapping cannot be used for both [placeholder].awrcloud.com and app.advancedwebranking.com, under the same account / subscription, even if 2 different subdomains are configured.
In this case, we recommend migrating the AWR subscription accordingly.
