Domain name is Invalid

[GyanRoutaray]

Hi Team,

We are using the bazaar voice SDK to add a review to the product in our mobile application. This SDK has been working for a long time and it suddenly stopped working. Now we are getting the below mention error from the submit review api :
API: https://api.bazaarvoice.com/data/submitreview.json
We are using HostedAuthentication_callbackUrl in mobile application: "https://rewards.sony.com"
Error:[{
"Message":"Invalid domain name: rewards.sony.com"
"Code":"ERROR_PARAM_INVALID_PARAMETERS"
}]
It was working earlier but few days back we are getting this error. Could you please let us know the exact root cause for this error.

We have the same functionality in web also. We tried to use their HostedAuthentication_CallbackUrl and then we are able to submit a review but when we try to confirm your review submission step. Its not getting loaded.

Thanks in advance.
